It is separated from the standard MRC part number by several spaces.MRC Manufacturing Suffixes MRC Manufacturing Suffixes The manufacturing suffix is specified on packing lists. Example: 204SZZ H501 Standard MRC Part No. This suffix is assigned sequentially within the MRC computer system and can only be cross-referenced internally by the MRC Customer Service Representative. The use of a non-descriptive manufacturing suffix permits minor changes to the design and manufacture of standard product without a confusing nomenclature change. The revised product may still be tracked through distribution by the four digit manufacturing suffix. Manufacturing Suffix A four digit manufacturing suffix is used by MRC internally to define bearing specifications as well as to track such information as plant-of-manufacture as product is distributed throughout the MRC warehousing network. Whenever possible the manufacturing suffix is also shown on the bearing steel. 29 . invoices and all unit cartons.

There is little that can be done to reduce the external loads. Reduced Wear from Vibration In equipment exposed to static vibration. Without proper attention to these external factors. The natural insulating properties of ceramic material eliminates this type of damage. Fluting created by electrical arcing Wear caused by static vibration conditions or. Bearings can fail if the initial grease charge is not replenished within an acceptable period of time. the service life of a hybrid bearing is up to 10 times that of a standard steel bearing. And longer service life reduces the need for maintenance on your machine as well as the costly interruptions in production. This provides cooler running for the same operating 55 . there is little evidence of adhesive wear as seen in steel bearings. since ceramic balls have only 40% of the density of steel balls. a steel bearing rarely reaches its design L10 life and therefore has a shortened service life. if applicable. contamination and maintenance. standard bearings experience surface wear because of insufficient lubricant film. Lower Operating Temperatures The heat generated in bearings is attributable to viscous friction from lubrication and load dependent friction between the balls and raceways. Less friction also results in lower energy costs. Anything that extends the service life of a bearing without increasing maintenance costs will reduce the operating cost of the equipment. Reduced Wear from Contamination In contaminated environments. the difference is quickly recovered in maintenance savings. Lower Maintenance Costs Maintenance costs can quickly add up if a bearing must be changed frequently. there is an inherent risk of false brinelling. However. which extends the bearing service life. Besides the surface damage. the centrifugal load generated by the balls is less and the internal friction is lower. This reduces the noise and wear. Extended Grease Life In environments that place high demands on the bearing lubricant. a higher rotational speed while maintaining the same temperature. The source of the loading is external as well as internal. (the wearing away of the surfaces within the ball and raceway contacts) which can eventually lead to spalling and premature failure. Also.Hybrid Ceramic Ball Bearings Prevents Electrical Arcing When electrical current passes across bearings. so there is less aging of the grease and the required relubrication interval will be longer. a washboard or fluting pattern appears on the raceways. The result is increased service life compared to standard bearings in the same operating conditions. Though the initial cost of a hybrid bearing is higher than a standard steel bearing. the risk of false brinelling damage is much less. Because of the lighter weight ceramic balls and dissimilar materials. Because of the properties of ceramics. solid particles create dents in the rolling surfaces and raised edges around those dents. Extended Service Life Most bearings are designed into applications based on loading conditions and do not take into account factors such as lubrication. Hybrid bearings run cooler and can operate with thinner lubricant films. The harder ceramic ball material smooths the surface roughness with no material removal. This condition causes noise and premature wear as the steel balls roll over those surfaces. premature aging of the lubricant also occurs. This damage usually results in excessive noise which requires that the bearing be removed. in addition to a darkened grey appearance. 4 x 10-6 (conductor) 1012 (insulator) The ceramic balls break the electrical current (DC) path and act as an insulator Relative dielectric constant N/A 4.

The nut is then removed. When using either of the above methods. The bearing will straighten up on its seating. adapter sleeve or withdrawal sleeve. One method of measuring the internal clearance of self-aligning ball bearings is shown in the illustrations below. The bearing will then have the requisite interference fit. When mounting bearings with C3 clearance. A washer A is inserted between the bearing and the shaft or sleeve nut to ensure correct alignment of the outer ring with respect to the inner ring. Another method which is often used to mount bearings with a tapered bore correctly and reliably is to measure the axial displacement S of the inner ring on the tapered MRC Bearing Services seating. The mounting of self-aligning ball bearings with tapered bore calls for experience and skill as they have a relatively small internal clearance. The bearing is then pushed on to the sleeve and the nut screwed on. A dial gauge B placed on the bearing outer ring can be used to measure the bearing clearance. tightened and locked by bending down one of the tabs of the locking washer. As the bearing has a tendency to skew when being pressed up it is advisable to reposition the hook spanner in a slot at 180˚ to that used for tightening and then apply a light hammer blow to the spanner. the thread of the nut and the side face of the nut which is to abut the bearing should be smeared with a molybdenum disulphide paste or similar lubricant. Before mounting. the locking washer inserted and the nut replaced. and a reliable measurement of the clearance reduction is not always possible. Guideline values for the tightening angle α are given in the table overleaf. By turning the nut through the given angle α the bearing will be pressed up on the tapered seating of the sleeve. When mounting bearings with Normal radial internal clearance it is generally sufficient to check clearance reduction during the drive-up by turning and swivelling out the outer ring. the residual internal clearance may be too small for the application. and the outside diameter of the sleeve should be lightly oiled. The outer ring should be pushed upwards in the direction of the shaft. and a bearing with C3 radial internal clearance should be used instead. As a measure of the° of interference of the fit. In some cases. . When the bearing is properly mounted the outer ring can be easily turned but there should be a slight resistance when the ring is swivelled out. the self-aligning ball bearings should always be pushed up on to the tapered seating until the bore of the bearing is in contact with the seating on the shaft or sleeve around its whole circumference. The procedures and values given in the following also 80 apply to bearings with Normal clearance. however. before the final tightening procedure is begun. The residual clearance of the bearing should be checked. Guideline values for the requisite displacement S are given in the table overleaf. A sufficiently tight fit will then be obtained and the residual clearance will correspond to the mean values given in the table. either the reduction in radial internal clearance of the bearing or the axial displacement of the inner ring on the tapered bearing seating can be used. the tightening angle α or the axial displacement S can be used to measure the° of interference.Self-Aligning Ball Bearings Mounting bearings with tapered bore Bearings with a tapered bore are always mounted with an interference fit on the shaft. An easy method of mounting bearings on adapter sleeves is based on the tightening angle α through which the nut is turned and the procedure is described in the following. 012 .30 .028 .41 .31 .021 .30 .016 .54 .017 .018 .22 .9370 4.017 .5748 1.018 15 20 20 6 8 8 30 40 40 12 16 16 85 90 95 3.54 .40 .40 .31 .015 .021 .23 .016 .7244 120 .009 .54 .59 .012 .9843 1.1654 2.009 .Self-Aligning Ball Bearings Mounting self-aligning ball bearings with tapered bore Bearing Bore Tightening Angle d α Axial Displacement S Mean Residual Clearance After Mounting Bearing Series Degrees mm .39 .69 .001 mm in mm mm 2300K 81 .67 .34 .015 .023 .45 .024 .58 .012 .66 .58 .40 .60 .47 .012 .5433 3.018 .016 .7402 120 120 120 .021 .60 .59 .023 .026 .009 .023 .30 .016 .46 .58 .33 .31 .58 .009 .012 .41 .54 .009 — .40 .45 .22 .67 .60 — .023 20 20 20 8 8 8 40 40 40 16 16 16 100 105 110 3.0001 in mm in in .43 .012 .22 — .013 .016 .46 .39 .59 .001 mm .3780 1.30 .023 .013 .016 .021 .009 .019 .012 .009 10 10 10 4 4 4 20 20 20 8 8 8 70 70 70 .024 .40 .024 .012 .9685 2.7874 .3307 120 120 120 .023 — .59 — .66 .013 10 10 15 4 4 6 20 20 25 8 8 10 1.026 .47 .33 .23 — .009 .009 .1339 4.22 .30 .016 .22 .23 .40 .39 .018 .019 .30 .009 — .34 .015 .9528 3.30 .027 20 25 25 8 10 10 40 55 55 16 22 22 120 4.70 .23 .3622 70 90 90 .012 .016 15 15 15 6 6 6 25 30 30 10 12 12 65 75 80 2.016 .41 .026 .023 .026 .30 .012 .013 .7717 50 55 60 2200K 1300K 1200K in C3 .43 .024 — .012 .67 .012 .1496 90 120 120 .0001 in in .31 .023 .1811 70 70 70 35 40 45 1.60 .026 — — — — — — 25 10 55 22 20 25 30 mm Normal .3465 3.5591 2.23 . 82 .

ABEC-3 bore tolerances reduce the range of interference fits between the shaft and bearing bore. and the 40° contact angle results in high thrust load carrying capacity. The low shoulder diameters on the nonthrust sides of the inner and outer rings. optimum race groove depth. These tighter tolerances result in closer control of preload and minimize the risk of thermal runaway. Because of this construction. They should not be used where the bearing is subjected to radial load only. allow for large quantities of oil to flow through these bearings. combined with large clearances between the land diameters and the cage. When heavy thrust must be taken in both directions. The increased oil flow reduces operating temperature and theoretically increases bearing life.7000-PJ Series Single-Row 40° Angular Contact Ball Bearings MRC angular contact ball bearings with a PJ suffix have one heavy race shoulder and one counterbored race shoulder on the outer ring. MRC 7000-PJ Series bearings are particularly suitable for positions where the thrust is always present in one direction. or combined radial and thrust load where the radial load is predominant. 024 .

For identification purposes. As a result. and other applications subject to thrust loads operating at relatively high speeds. gyroscopic forces in the unloaded bearing can cause the balls to rotate perpendicular to their true rolling axis and momentarily lose contact with the raceway. resulting in reduced operating temperatures and increased life. The outer ring surface of the set is marked with a “V” pointing in the direction of primary thrust. NOTE: The basic radial load rating. making it less susceptible to the gyroscopic forces which result in ball sliding or shuttling. C. Angular contact bearings used in high speed (e. Dimensional stability is assured by heat treating the bearing’s rings and rolling elements for operation up to 375˚F (190˚C). Without axial load. The 15° bearing also provides additional radial stiffness helping to maintain the integrity of the shaft and mechanical seals. matched sets of 40° angular contact ball bearings are used to obtain maximum theoretical fatigue life. The main benefit of the PumPac system is that the 15° (B) bearing is designed with considerably less internal clearance than the 40° (A) bearing. The 40° (loaded) bearing provides sufficient axial rigidity under the imposed thrust load. which consists of a matched set of 15° (B) bearings in a back-to-back arrangement. lightly loaded applications in which axial loads are balanced. producing friction and heat which lowers oil viscosity and accelerates wear. At the heart of these premature failures are phenomena known as “ball sliding” and “ball shuttling” in the unloaded (or inactive) bearing.

The bearings are mounted so that the 40° (A) bearing takes the primary thrust load. For applications involving very heavy primary thrust loads. a microscopic wear (or lapping) process occurs giving the appearance of a burnished or polished raceway. The PumPac is also available in the 8000BB PumPac Diamond series. 3600 RPM) pumps and other applications require a minimum axial load for proper operation. the marking on the outer ring surface forms a diamond.

These bearings have the same nominal external dimensions as equivalent size ABEC-1 grade bearings; however, the running characteristics and external dimensions are held to closer tolerances. Standardization Bearing envelope dimensions and tolerances shown in this catalog comply with standards established in the USA by the Annular Bearing Engineers Committee (ABEC) of the American Bearing Manufacturers Association (ABMA) (see Engineering section; page 239). These standards have also been approved by the American Standard Association (ASA) and the International Standards Organization (ISO). This assures the bearing user of all the advantages of dimensional standardization. However, dimensional interchangeability is not necessarily an indication of functional interchangeability. Other characteristics must also be considered such as cage type, internal clearance, contact angle, configuration of the bearing rings and other details. Temperature The bearings are manufactured from vacuumprocessed 52100 steel that can operate satisfactorily to 250˚F (121˚C). This is well within the requirement of most machine tool applications. Duplexed Bearings Precision ball bearings are also duplex ground so they can be used as a component in a pair of bearings or in a bearing set (see Duplex Bearings section; page 234). Duplex pairs (or sets of bearings) ordered as DB, DF, or DT (or in combinations), are tied together as they are to be mounted. Packaging and Identification Bearings are thoroughly cleaned immediately prior to packaging and are usually coated with a lightweight oil compatible with most machine lubricants. Therefore, bearings can be used as received without being washed, with the oil serving as a rust inhibitor. Singlerow bearings are packaged in hermetically sealed transparent bags and placed in distinctive boxes identified with the bearing number, tolerance grade and other important bearing data. In order to meet the running characteristic tolerances specified for precision bearings, it is necessary to assemble them with high precision balls where the size, sphericity and other surface characteristics are held to very close tolerances. Cages generally are of phenolic (bakelite) composition, which is well-suited for highspeed operation.

Recommended mounting fits are shown on pages 258 to 259 in the shaft and housing fit section. pressed brass. As a result of actively participating in this market for many years. The 60 ˚ contact angle contributes to maximum axial rigidity and gives very stiff screw support to maintain the accuracy of the ball screw. For even stiffer screw support. the bearings can be mounted in quadruple sets. These bearings are made in ABEC-7 tolerance grade only. These ball screw support bearings are designed for use in numerically controlled machine tools where standard angular contact bearings or roller bearings cannot deliver the rigidity levels required. Construction and ring design permit a greater number of balls than the standard angular contact types. The 60˚ initial contact angle provides maximum axial rigidity.Ball Screw Support Bearings Duplex DF Quadruplex DFDT The MRC ball screw support bearing is a single-row angular contact nonseparable bearing with one heavy race shoulder and one counterbored race shoulder on the outer ring. The inner ring is similar in design having a counterbored race shoulder. and result in a very high thrust load-carrying capacity. Inner and outer rings and balls are of AISI 52100 steel. ball-riding cages are supplied with ball screw support bearings. these angular contact bearings are mounted in duplex pairs. Retainers are a ball-riding type of molded polyamide composition. As heavy thrust must be taken in both directions.

Duplex bearings are ordinarily supplied as half pairs unless they are high precision machine tool bearings that typically come in pairs. Combinations of three or more bearings are also available. MRC duplex bearings may be used to advantage in applications where: 1. Axial and radial deflections must be held to a minimum; 2. Maximum radial capacity is required; 3. Heavy single direction or reversing thrust loads must be supported; 4. Axial shaft location must be maintained under reversing thrust loads; and 5. Moment loading is present. Standard Methods of Mounting Duplex bearings can be mounted in three different ways to suit different loading conditions and requirements for rigidity. The three different positions bear the identification symbols ‘‘DB,’’ ‘‘DF,’’ and ‘‘DT.’’ MRC Bearing Services DF—Face-to-face This sketch shows the face-to-face (DF) position, where the two halves are placed so that the contact angle lines of the two bearings are converging inwardly. For all MRC duplex bearings, this means that the unmarked faces of the outer rings are together. On all angular contact and Type R bearings, the low shoulder sides of the outer rings will be adjacent. The DF position may be used to advantage where the duplex pair carries: (1) a heavy radial load; (2) a combined radial and thrust load; (3) a reversing thrust load. This mounting arrangement allows the bearings to handle a small amount of misalignment. DF pairs are axially clamped in the housing and on the shaft. DT—Tandem DB—Back-to-back The sketch above shows the back-to-back (DB) position where the two halves are placed so that the contact angle lines of the two bearings diverge inwardly. For all MRC Duplex bearings, this means that the marked faces of the outer rings are adjacent. 7000 Series and Type R bearings have the low shoulder sides of the outer rings facing outward. A DB pair may be used to carry: (1) heavy radial loads; (2) combined radial and thrust loads; (3) reversing thrust loads; (4) moment loads. Due to its construction, the DB pair has great angular rigidity and may be used in applications where it is necessary to restrict misalignment or shaft deflection. DB pairs are axially clamped on the shaft but may float in the housing to provide for thermal expansion. 234 This illustration shows the tandem mounting arrangement, where the two halves are placed so that the contact angle lines are parallel. For all MRC duplex bearings, this means that the stamped face of one bearing is in contact with the unstamped face of the other bearing. The DT mounting is used to carry extremely high thrust loads in one direction where high speeds or space limitations prevent the use of a larger bearing. Special Methods of Mounting Duplex Bearings The three methods of mounting duplex pairs—DB, DF, and DT—are basic. However, other combinations may frequently be used to advantage. A few of these combinations are shown below. DB Pair Separated by Spacers Duplex Stack of Three Bearings (1¹⁄₂ Pair) Mounted in Tandem This arrangement shows three bearings mounted in the tandem relationship and will provide greater thrust load carrying capacity, since three bearings are sharing the thrust load. It is sometimes desirable to separate duplex bearings by equal length spacers mounted between the two inner rings and the two outer rings. This mounting arrangement is desirable when the pair is subjected to a heavy moment load, when it is necessary to minimize shaft deflection, or when the bearings are running too hot next to each other. Care should be taken to make certain that these spacers are parallel and equal in length. Single Bearings (¹⁄₂ Pair)—DU, DS, DE Additional thrust carrying capacity may be obtained by increasing the number of bearings in the stack. Duplex Arrangement of a DT Pair Mounted in DB Relationship with a Single Bearing An arrangement such as this will provide extremely high load-carrying capacity in the direction of the heavy outer ring shoulder of the two tandem mounted bearings as well as considerable reversing thrust. If the thrust load in both directions is equal in magnitude and duration, an arrangement of four bearings could be used in which a DT pair would be mounted in DB relationship to another DT pair. The set would have the suffix DTDB. MRC bearings with controlled axial relationship of faces are available as single bearings (1/2 pair). They are ordinarily specified when the customer uses duplex bearings in a number of different mounting arrangements and wishes to simplify the problem of stocking prearranged pairs. Single duplex bearings are ground for universal mounting and may be matched with any other bearing from a carton having identical markings. Type DU bearings have flush ground faces and when mounted in pairs and clamped, have neither preload nor end play. Type DS bearings are furnished with preload and are also identified on the bearing with the designation DL, DM, DH or DX for light, medium, heavy, or special preload respectively. Type DE bearings are furnished with end play as clamped and are also identified on the bearing with the designation CA, CB, CC or CX for specific end play values with CX calling for special end play. Duplex Arrangement of a DT Mounted in DF Relationship with a Single Bearing This arrangement provides the same capabilities as the DB mounting except the bearings are mounted in a DF relationship. The set would have the suffix DTDF. 235 Duplex Bearings MRC Bearing Services Interchangeability Before Clamping Preloaded Bearings Preloaded duplex pairs are made from single bearings having inner and outer rings of equal width but in which the stamped face of the outer ring protrudes beyond the face of the inner. The sketches show this relationship for a DB pair. ‘‘A’’ is known as the bearing offset. Types DU, DS and DE (single bearings) may be mounted in the DB, DF, or DT relationship. However, these bearings should not be used with bearings from any other box unless the markings on both boxes are identical. In the case of making replacements for bearings which have been installed and run, we recommend that both bearings be replaced. This avoids the dangers involved in attempting to match two bearings, one of which has unknown internal characteristics. Shaft and Housing Fitting Practices The control of the axial location of inner and outer ring faces found in all duplex bearings is dependent upon the internal clearance in the bearing. A change in internal clearance will result in a change in the flushness or offset of the faces. Clamped When the inner and outer rings are clamped together an elastic deformation takes place in the contact between the balls and races. Since the deflection rate of a bearing decreases with increasing load it is possible to eliminate the major portion of the potential deflection of a bearing under load through preloading. In order to suit the customers’ application requirements MRC bearings are available with light, medium, heavy or special preload. Please consult our Technical Services Department for the proper selection of preload. End Play Duplex pairs with end play are made from single bearings having inner and outer rings of equal width but in which the face of the inner protrudes beyond the stamped face of the outer. End play in duplex pairs is desirable where there is misalignment, high operating temperatures or when the bearings are mounted with a heavy press fit on the shaft and/or in the housing. 236 In mounting a duplex pair, it is particularly important that excessive press fits on the shaft or in the housing be avoided. Otherwise, the individual bearings in the set will be axially preloaded against each other which might result in excessive heating and early failure. In those cases where heavy press fits are imperative, duplex sets with end play should be used. Refer to page 248 for mounting recommendations. Packaging Types DB, DF, and DT duplex pairs are ordinarily supplied wired together in the same relationship as they are to be used. The pair is then packaged together and the carton is stamped with the appropriate symbol. Types DU, DS, and DE (single bearings) are typically packed separately. If special packaging is required, please consult MRC’s Application Engineering group. Duplex Bearings 97000U and 97000UP Series Mounting Orientation The 97000U Series consists of a matched set of 9000UDT (split inner ring) and 7000DT flush ground bearings having a 29° contact angle. The 97000UP Series consists of a matched set of 9000UPDT (split inner ring) and 7000PDT flush ground bearings having a 40° contact angle. Caution: To obtain proper load distribution, it is necessary to orient mating bearing ring faces, and the inner ring halves of the split ring bearing (9000UDT), according to the illustration below. The counterbored outer ring bearing (7000DT) can be mounted either at side (A) or side (B) of the split ring bearing as shown. Typical Mountings The bearings are usually mounted in pairs. This arrangement divides the thrust load in one direction while accommodating reversing thrust load. To increase thrust capacity in one direction it is possible to mount additional bearings in tandem. The number of bearings in the set will be identified by a number at the end of the bearing designation. For example, a set of three bearings (triplex) is identified as the 97000U3 and a set of four (quadruplex) as the 97000U4. Numbers 2 through 9 only will apply. Numbers 10 and higher indicate some special characteristic. Illustration of typical mountings are shown below. In addition, each bearing in the set will be marked with a ‘‘V’’ etched on the outer ring surface with the apex pointing in the main shaft thrust direction. Notes: The numbers ‘‘1’’ and ‘‘2’’ marked on the bearing with the split inner ring, are to keep the proper relationship between the inner rings and the outer ring. The counterbore bearing(s) can be mounted either side (A) or (B) (above or below) the split bearing provided that the ‘‘V’’’s marked on the O.D. of bearings are pointed in the direction of the ‘‘Primary Shaft Thrust’’. 97000U2 97000U4 Bearing Identification Marking The box and bearings will be marked according to the following example. Bearing size: 97314UP2 Box: 97314UP2-BRZ 0001 BRZ = Machined Bronze Cage 0001 = MRC Specification Code Suffix Bearing: All bearings in the set will be marked 97314UP2 0001 Previous marking: The bearing set was identified on the box as 9314UPDT/7314PDT; and on the bearings as 9314UPDT and 7314PDT. 237 238 ABEC 1 ABMA/ISO Tolerances for Single-Row, Double-Row, and Duplex Bearings Tolerances in inches (shaded) and millimeters.

A satisfactory radial location and an adequate support can generally only be obtained when the rings are mounted with an appropriate° of interference. However. For the inner ring the fit recommended for rotating load is normally used. shock loads. a bearing ring will not normally turn on its seating. Inadequately or incorrectly secured bearing rings generally produce damage to the bearings and associated components. interference fits must be used. for inner rings. The reduction in clearance due to the interference fit can be so large that bearings with increased radial clearance have to be used in order to prevent the bearing from becoming preloaded. or if the ring is stationary and the load rotates so that all points on the raceway are subjected to load in the course of one revolution. interference fits cannot be used. its rings or washers must be supported around their complete circumference and across the whole width of the raceway. for washers. the load is defined as a ‘‘rotating load’’. when simple mounting and dismounting are desirable. Magnitude of the load. or when axial displacement is required with a nonlocating bearing. The interference fit of a bearing inner ring on its seating will be loosened with increasing load as the ring will expand. Variable external loads. A bearing ring subjected to a rotating load will turn (creep) on its own seating if mounted with a clearance fit. However. particularly if it is of shock character. 2. Essentially there are three different conditions: ‘‘rotating load’’ ‘‘stationary load’’ and ‘‘direction of load indeterminate’’. holes or other features. When interference fits are used on both the inner ring and outer ring. internal preloading. the remaining internal clearance of the bearing should be considered to avoid excessive clearance reduction. A certain minimum clearance should remain. Heavy loads which do not rotate but oscillate (for example. The initial clearance and permissible reduction depend on the type and size of the bearing. while outer ring expansion may prevent the desired axial displacement of the ring in its housing. 3. bearing rings normally reach a temperature which is higher than that of the components to which they are fitted. This means that the seatings must be made with adequate accuracy and that they have a surface which is uninterrupted by grooves. when the outer ring must be free to move axially in the housing and the load is not heavy. To prevent this. those acting on the outer rings of connecting rod bearings) are generally considered as rotating loads. 246 MRC Bearing Services When a stationary load exists. When the direction of load is indeterminate and particularly where heavy loads are involved.e. can be provided by a cylindrical or tapered seating or. Bearing internal clearance An interference fit of a bearing on the shaft or in the housing means that the ring is elastically deformed (expanded or compressed) and the bearing internal clearance reduced. and wear (fretting corrosion) of the contacting surfaces will occur. If the bearing ring rotates and the load is stationary. the greater the interference required.Shaft and Housing Fits Radial Location of Bearings If the load carrying ability of a bearing is to be fully utilized. the factors discussed in the following and the general guidelines in respect of them should be considered. 5. The° of interference needed is dictated by the operating conditions (see points 2 and 4). 4. or if the ring and load rotate at the same speed so that the load is always directed to the same point on the raceway. a somewhat looser fit than that recommended for rotating load may be used. The support must be firm and even and. Such conditions are classified as ‘‘direction of load indeterminate’’. Temperature differentials and the direction of heat flow must therefore be carefully considered. Selection of fit When selecting a fit. by a flat (plane) support surface. Bearing seatings on the shaft and in the housing should be made to narrow . page 270). vibrations and unbalance loads in high-speed machines give rise to changes in the direction of load which cannot be accurately described. 1. Under the influence of rotating load the ring may begin to creep. Running accuracy requirements To reduce resilience and vibration. In addition the rings must be reliably secured to prevent them from turning on or in their seatings under load. The° of interference must therefore be related to the magnitude of the load: the heavier the load. ‘‘Stationary load’’ applies if the bearing ring is stationary and the load is also stationary. however (see also ‘‘Bearing radial clearance’’. i. it is desirable that both rings have an interference fit. Temperature conditions In service. This can result in an easing of the fit of the inner ring on its seating. Therefore. Conditions of rotation Conditions of rotation refer to the movement of the bearing ring being considered in relation to the direction of the load. clearance fits should generally not be used for bearings where high demands are placed on running accuracy. the ring need not necessarily have an interference fit unless this is required for other reasons. This is ensured by adopting a clearance fit for that ring which carries a stationary load. Displacement of non-locating bearing If non-separable bearings are used as non-locating bearings it is imperative that one of the bearing rings is free to move axially at all times during operation. If cylindrical or needle roller bearings having one ring without flanges are used. When the outer ring is under stationary load so that axial displacement has to take place in the housing bore. or bearings with tapered bore and adapter or withdrawal sleeve may be used. for example. 7.Shaft and Housing Fits Radial Location of Bearings (continued) made to narrow dimensional tolerances. Design and material of shaft and housing CAUTION: The fit of a bearing ring on its seating must not lead to uneven distortion of the ring (out-of. In this way a ‘‘hammering out’’ of the housing seating because of the lower material hardness is avoided.round). corresponding at least to ABEC-5 for the shaft and ABEC-3 for the housing as shown in the tables. 6. This can be caused for example by discontinuities in the seating surface. separable bearings. both bearing rings may be mounted with an interference fit because axial displacement will take place within the bearing. heavier interference fits than those normally selected for thick-walled steel or cast iron housings or for solid shafts should be used (see also ‘‘Fits for hollow shafts’’. where light alloy housings are employed. reduced shaft interference or increased bearing internal clearance should be considered because of the high coefficient of expansion of stainless steel. For stainless steel shafts. a hardened intermediate bushing is often fitted to the outer ring. 247 . 8. it would otherwise result in the axial displacement being restricted or even impossible after a time. light alloy housings or on hollow shafts. Split housings are therefore not generally suitable where outer rings are to have an interference fit. To ensure adequate support for bearing rings mounted in thin-walled housings. Where operating conditions necessitate interference fits and it is essential that mounting and dismounting can be done easily. Ease of mounting and dismounting Bearings with clearance fits are usually easier to mount or dismount than those with interference fits. page 248). Loss of internal clearance changes the bearing preload that can lead to excessive heating and premature failure. If 248 different shaft materials are being used. the recommended shaft and housing tolerances are “h5” and “H6” respectively. DU.

MRC Application Engineering should be contacted in order to select more appropriate fit tolerances.3 for all other bearings To determine the requisite interference fit for a bearing to be mounted on a hollow shaft. The PJDE suffix would indicate a bearing specifically designed for paired mounting and axial endplay or looseness. the diameter ratio ce can be calculated with sufficient accuracy from the equation ce = d k (D – d) + d where d = bore diameter of bearing D = outside diameter of bearing k = a factor for the bearing type k = 0. For special bearing applications and arrangements. the fit of the inner ring is not determined by the selected shaft tolerance but by the distance through which the ring is driven up on the tapered shaft or sleeve.0001 inch . signifying light. “DM”. These recommendations are valid for solid steel shafts and cast iron or steel housings. “CC”. They apply to single-row. However. For the recommended mounting procedure refer to pages 80 and 81 in the self-aligning ball bearing section. 7200PJDU. then the effective interference can be equated to the mean probable interference. Duplex Bearings MRC 7000PJ series. double-row and duplex bearings mounted on steel shafts and in steel or cast iron housings. use is made of the mean probable interference between shaft diameter and bearing bore obtained for the tolerance recommended for a solid shaft of the same diameter. Fits For Hollow Shafts If bearings are to be mounted with an interference fit on a hollow shaft it is generally necessary to use a heavier interference fit than that used for a solid shaft in order to achieve the same surface pressure between the inner ring and shaft seating. If the plastic deformation (smoothing) of the mating surfaces produced during mounting is neglected. bearings are supplied in several different clearance/preload classes.

The other ranges include the “CA”. without any additional suffix code letters is equivalent to a “CB” clearance range (see table below). 249 . ∆V equals the mean value of the smallest and largest values of the probable interference given in the tables. Example: A 208S deep groove ball bearing is to be mounted on a hollow shaft having a diameter ratio of Ci = 0. Shaft And Housing Surface Finish For ABEC-1 bearings. Thus the required interference for the hollow shaft is.8.3 (80 – 40) + 40 = 0.Shaft and Housing Fits The interference ∆H needed for a hollow shaft of steel can then be determined in relation to the known inteference ∆V for the solid shaft from the diagram below. The recommended mean probable interference for a solid steel shaft is 0.7 from the diagram.7 × . For C = 0. Housing bores should not exceed 125 AA. finishes should not exceed 32 AA for shafts up to 2 inches in diameter and 63 AA maximum over 2 inches.8 and C = i e The ratio ∆H / ∆V =1. ∆H =1.

The basic dynamic load rating C and the basic static load rating Co are quoted in the bearing tables. are subjected to very slow oscillations. sub-surface metal fatigue cracks occur which eventually propagate to the raceway surface causing metal flaking. or stationary under load. at which time the bearing has achieved its useful life. It expresses the bearing radial load which will give a basic rating life of one million revolutions. They apply to radial loads acting on radial and angular contact bearings which are constant in magnitude and direction. The imposed load produces rolling element and raceway deformation as illustrated in figure 1. As these stress cycles are repeated. the radial load rating refers to the radial component of that load which causes a purely radial displacement of the bearing rings in relation to each other. The actual calculated life depends on the magnitude of the imposed load. resulting in tensile (t) and compressive (c) stresses as each rolling element passes through the loaded zone. Figure 2 271 . For this contact stress. Dynamic Radial Load Rating The basic dynamic load rating C is used for calculations involving the selection of bearings which rotate under load. Numerical values of basic load ratings are used in calculations to express load carrying capacity. For single row angular contact bearings. It also must be considered when heavy shock loads of short duration act on a rotating bearing. Figure 1 The basic dynamic radial load ratings of MRC Bearings have been determined in accordance with the latest ISO and ABMA standards and are based on the material and manufacturing techniques used for MRC standard production. The basic static radial load rating is defined in accordance with ISO and ABMA standards as the static radial load which corresponds to a calculated contact stress at the center of the most heavily loaded rolling element/raceway contact of 609000 PSI for all radial and angular contact ball bearings.0001 of the rolling element diameter as shown in figure 2. as determined by the number of revolutions of calculated life.Definition of Dynamic and Static Radial Load Ratings The size of a bearing to be used for an application is initially selected on the basis of its load carrying capacity in relation to the loads to be carried and the requirements regarding life and reliability. or spalling. All values expressed are radial ratings. a total permanent deformation of rolling element and raceway occurs which is approximately 0. Static Radial Load Rating The basic static radial load rating Co is used when bearings rotate at very slow speeds. It is the result of contamination.MRC Bearing Services Definition of Bearing Life The life of a rolling bearing is defined as the number of revolutions or the number of hours at a given speed which the bearing is capable of enduring before the first sign of fatigue failure occurs on one of its rings or rolling elements. there will be considerable variation in the fatigue lives in the group. The life which 90% of a group of bearings will exceed is known as the ‘‘minimum life’’ or ‘‘rating life’’. The life which 50% of a group of bearings will exceed is the ‘‘median life’’ (L50) and is approximately five times the ‘‘minimum life’’.. corrosion. misalignment. The actual life of a specific bearing is referred to as ‘‘service life’’ and unlike ‘‘minimum’’ or ‘‘rating’’ life. Life Adjustment Factor for Reliability. The rating of these bearings has been modified to reflect raceway curvatures less than a total of 54 percent.

As a result. the L10 life must be multiplied by the factor a1 as shown in the table below. A commonly used term as used in this catalog is ‘‘L10’’. The load ratings shown in this catalog are based on the useful life of a bearing as limited by this type of failure.62 0. is not generated by fatigue.44 0. Determination of Bearing Life Bearing ‘‘rating life’’ can be calculated by referring to the procedure and examples located at the back of each bearing section. the static load rating is that load which produces a total permanent deformation of the rolling element or raceway which is approximately 0. rotate or oscillate very slowly or subjected to heavy shock loads.0001 of the rolling element diameter. with the exception of Mast Guide and PumPac bearings. the basic static load rating (Co) must not be exceeded. life must be treated statistically. etc. a1 To determine bearing life in accordance with reliability greater than 90%.

Any increase in speed above the speed rating without taking any of these precautions would only cause the temperature to rise excessively. More detailed information will be supplied on request. all components. The base oil viscosity and thickener determine the shear strength of the lubricant. under normal loading conditions there is a balance between the heat which can be removed from the bearing via the shaft and housing and sometimes via the lubricant and the heat generated in the bearing by friction at acceptable temperature interval above ambient. at the same time. For satisfactory bearing operation. by cooling ribs on the housing or by directed cold air streams. lubrication of cage guiding surfaces. Speed ratings Speed ratings for grease and oil lubrication are quoted in the bearing tables. that sets the limit. the friction in the bearing will be increased so that the bearing cannot be operated at such high speeds as the speed rating would indicate unless higher temperatures can be permitted. Speeds above the speed rating It is possible to operate bearings at speeds above the speed ratings given in the bearing tables if the bearing friction can be reduced by lubrication considerations or when heat can be removed from the bearing by circulating oil lubrication with cooling of the oil. load. Another limit is set with grease lubrication by the grease used. The speed limit as defined by the speed rating is the first limit to be reached with almost all bearing types. Bearing type and size. If. Some reduction may be necessary where bearings are to operate with rotating outer ring. . depending on bearing type. When heavier loads are applied to the bearing. centrifugal and gyratory forces acting on the rolling elements and other speed-limiting factors. particularly those which rotate. The multiplying factors shown in the footnotes are based on historical application and experience. must have a higher accuracy than normal to take account of the vibrating behaviour. thus leading to higher friction and further temperature increases. other criteria have a stronger influence. especially at high speeds. internal design. accuracy and internal clearance all play a part in determining the permissible speed. which in turn determines the permissible operating speed for the particular bearing. an internal clearance greater than Normal (C3) is required. the final consequence would be bearing seizure. Usually. therefore. Any increase in speed above the speed rating generally means that the temperature difference between inner and outer ring is greater than normal. a minimum load must be applied. the influence of heavier loads on the permissible speed is generally only of importance for large bearings (≥100mm). An increase of bearing temperature means that lubricant viscosity is reduced and lubricant film formation is made more difficult.Speed Rating There is a limit to the speed at which rolling bearings can be operated. Special cage designs may also be required and it is therefore advisable to contact MRC Bearing Services. 274 MRC Bearing Services the operational clearance in the bearing is reduced because of increased inner ring temperature. The speed at which this bearing temperature is reached depends on the frictional heat generated in the bearing (including any externally applied heat) and the amount of heat which can be transported away from the bearing. The speed ratings listed in the tables may be modified due to grade and cage variants. with respect to the lubricant being used or to the material of the bearing components. lubrication and cooling conditions as well as cage design. The speed rating for a given bearing represents the speed at which. The speed ratings apply to bearings where the inner ring rotates. However. For high speed bearing arrangements. These criteria include the form stability or strength of the cage. Generally it is the operating temperature which can be permitted. Above this limit. 275 . 276 . allows the bearing to run at much higher speeds. Steels for Temperature-Resistant Bearings MRC rolling bearings can generally be used at operating temperatures up to 250˚F (121˚C). In such cases it is advisable to contact MRC Bearing Services Engineering. The corrosion resistance is only available when the whole surface is perfectly polished and if it is not roughened or damaged during mounting. For more information on the different types of corrosion resistant steels and their application. Much development has been accomplished in the area of through hardened steels. The low thermal expansion of the ceramic balls makes them less sensitive to differences in temperature between the inner and outer rings. The higher modulus of elasticity makes the bearings much stiffer. This combination provides a bearing that has greater stiffness. Materials for Cages The main purpose of the cage is to keep the rolling elements at an appropriate distance from each other and to prevent immediate contact between two neighboring rolling elements in order to keep friction and thus heat generation in the bearing at a minimum. In fact. Steels for Bearing Rings and Rolling Elements Steels used for bearing rings and rolling elements must be capable of high fatigue strength and wear resistance.15% are those case-hardening steels most commonly used for rolling bearings. For bearings which are required to operate at temperatures in excess of 450˚F (232˚C) special steels with high hot hardness are required. there are a couple options. Inner or outer ring land guided machined cages generally permit operation at higher speeds and are necessary when movements additional 277 . Lower density combined with the reduced friction due to the ball’s smooth surface. Pressed steel or brass cages are generally guided on the rolling elements. Because of the reduced hardness of these steels. Particular attention has been paid to cleanliness and modern bearing steels have such small contents of inclusions that it is now recognized that under ideal conditions bearings should no longer fail from fatigue. Case-Hardening Steels Chromium-nickel and manganese-chromium alloyed steels with a carbon content of approximately 0. However. Because MRC has both the competence and the facilities for through hardening. it is recommended to contact MRC Application Engineering. The structural and dimensional stability of the bearing components must be satisfactory at the operating temperatures which can be expected. case hardening and induction hardening. there are applications where a particular type of steel has certain advantages.5% chromium. Historically. Steels for MRC Rolling Bearings In the majority of applications there is virtually no difference in behavior between bearings made of through-hardened or case-hardened steels. Steels for Corrosion-Resistant Bearings For bearings that come into contact with corrosive media during operation. The cage is guided either on the rolling elements or on one of the bearing rings and is thus radially centered. chromium or chromium/molybdenum stainless steel has been used. the bearings must be subjected to a special heat treatment (stabilization) so that inadmissible changes in dimensions do not occur as a result of microstructural changes. For bearing components having large cross sections steels alloyed with manganese and molybdenum are used because of their superior through-hardening properties. However. This fact has been acknowledged by ISO in that no distinction is made between steel types in the life calculation. In most cases the choice of a particular steel is dictated by the application requirements. attention is paid to the main application fields for each particular bearing and the steel and method of heat treatment are chosen to give the best performance in these applications.Materials and Limitations Materials for Rolling Bearings The performance and reliability of rolling bearings are determined to a large° by the materials from which the bearing components are made. The lower density of the silicon nitride ceramic balls creates less centrifugal force than steel balls. the bearings should not be stabilized for a higher temperature than the expected operating temperature. In grease lubricated bearings some of the grease inside the bearing will adhere to the cage forming a lubricant reservoir and ensuring good lubrication of the operating surfaces of the bearing. Some specialty high nitrogen steels have been developed which provide better corrosion resistant than the chromium stainless steels as well as the same high load carrying capacity as conventional bearing steels. If the operating temperatures are higher than this. steel cleanliness and proper manufacturing methods as well as bearing design are the decisive factors. is able to handle higher speeds and higher temperatures. Hybrid Bearings with Ceramic Balls MRC hybrid bearings use steel inner and outer rings with ceramic balls. the bearings do not have the same high load carrying capacity as bearings made of conventional steels. Through-Hardening Steels The most common through-hardening steel used for rolling bearings is a carbon chromium steel containing approximately 1% carbon and 1. These cages have relatively . The injection molding process used to produce the cages allows functionally suitable designs to be made.g. If the permissible temperature is exceeded. Molded Polyamide Cages For some bearing types. particularly when conditions of high acceleration prevail. At operating temperatures up to the values given in the adjacent table for the various oils and greases which are used as bearing lubricants. With reference to the viability of production.

The good sliding properties of polyamide on lubricated steel surfaces and the smoothness of the cage surfaces in contact with the rolling elements mean that little friction is generated by the cage so that heat generation and wear in the bearing are at a minimum. The standard cage is always well proven in service and is the design considered most suitable for the majority of applications.g. They may also be subjected to the chemical action of certain lubricants. the small and medium-sized bearings are available with molded cages of heat stabilized. machine oils. manufacturing methods. Thus the design and choice of material are of paramount importance for the performance of the cage as well as for the operational reliability of the bearing as a whole. 2)For sodium and calcium base greases and other bearing greases with a maximum operating temperature below 120˚C. Steel Cages Pressed cages of steel sheet are standard for many deep groove ball bearings. The excellent running properties of polyamide cages 278 under lubricant starvation conditions permit continued operation of the bearing for a time reducing the risk of seizure and secondary damage. calcium complex 120 248 1) Measured on the outside surface of the outer ring. the cages differ as to form.

Bearing steels are hard. other contact points on the ball slide or spin along areas of the raceway. and elasticity of the bearing materials. Technically the zones of pure rolling in #3 are very narrow but there are larger areas that approach pure rolling. ball size. One source of heat developed in a bearing results from these stresses and the deformation of the bearing material associated with them. some sliding friction is generated during operation of antifriction bearings. Race and rolling element finish are also critical since even minute surface imperfections can cause high stress concentrations resulting in premature failure. As examples. the cage slides against ring guiding surfaces. (See Figure 2) The amount of deformation is a function of the magnitude and direction of load. rolling contact surfaces and geometries are maintained to millionths of an inch. High friction generally creates high heat and thermal expansion. race geometry. When a cage is present the rolling elements slide against this and under some operating conditions. See Figure 1. It is unlikely that any other mass produced item is machined to such close tolerances. Successful operation of an antifriction bearing requires a lubricating film in the areas of sliding contact. the theoretical fatigue life is reduced to one-eighth. durable alloys. a. pure rolling occurs only along two lines in the contact area. Without lubrication in the highly loaded contact areas. d. This frequently causes surface degeneration and early fatigue. if speed is doubled. When a ball under load rolls in a curved bearing raceway. Cage breakage may also result from extreme stresses. In operation. although less obvious. they must be sufficiently elastic to quickly regain their original shape after deformation through loading. even when loads are lighter and the ball paths narrower. MRC Bearing Services Bearing Construction An anti-friction bearing is a precision device and a marvel of engineering. c. The life of an anti-friction bearing running under good operating conditions is usually limited by fatigue failure rather than by wear. This is because the effective diameter of the ball is smaller at points distant from the bottom of the race-groove. The ball flattens out in the lower front quadrant and bulges in the lower rear quadrant. . highly free of impurities in order to withstand the high unit stresses which occur at the point of contact between a rolling element and the race. the theoretical fatigue is reduced to one-half. the fatigue life of a bearing is determined by the number of stress reversals and by the cube of the load causing these stresses.Lubrication of Anti-Friction Bearings Lubrication of Anti-Friction Bearings Introduction Although the basic principle of ball and roller bearings is the rolling of one element over another. usually concentrated in the rolling elements and inner ring races which may cause a loss of internal clearance and radial preloading. an elliptical area of contact results between the ball and the race. Also. slight deformation of both the ball and the race occurs. In cageless bearings. While boundary dimensions are usually held to tenths of a thousandth of an inch. Also. if the load on the bearing is doubled. It is for this obvious reason that very little surface degradation can be tolerated. The slippage in zone #1 is in opposite direction from that in zone #2. the rolling elements slide against each other. b. Under optimum operating conditions. These conditions exist. very high friction will be encountered in ball bearings. Figure 1 282 Principle of Operation Figure 2 When a ball in a bearing is subjected to load. The forces of slippage between zone #1 and the two zones #2 are equal in magnitude. Any particular point on the race goes through a cycle of these stress reversals as each ball passes it. Lubrication of Anti-Friction Bearings Friction Torque The friction torque in an anti-friction bearing consists essentially of two components. When the Kinematic Viscometer is used to measure oil viscosity. Advantages 1. Where a lubricant must dissipate heat rapidly. leakage is minimized where contamination of products must be avoided. In some cases. On the other hand. The unit of kinematic viscosity is the stoke or the centistoke (cSt). With more oil than just enough to make a film. less difficulty with leakage. The Saybolt Universal Viscosimeter measures the time in seconds required for 60cc of oil to drain through a standard hole at some fixed temperature. To provide a film of oil between rolling contact surfaces (elastohydrodynamic lubrication). To lubricate sliding contact between the cage and other parts of the bearing. The extensive use of grease has been dictated by the possibilities of simpler housing designs. The other is a function of the lubricant type. Being a solid when not under shear. Oil Versus Grease The ideal lubricant for rolling element bearings is oil. Viscosity 6. for ball bearings and cylindrical roller bearings. The common temperatures for reporting viscosity are 104˚F and 212˚F (40˚C and 100˚C). With grease lubrication. Simpler housing designs are possible. The single most important property of oil is viscosity. 3. To provide a sealing barrier against foreign matter. Extreme loads at low speed or moderate loads at high speed may create sufficient heat in the bearing to make grease lubrication unsatisfactory. Oil Characteristics 4. It has been found that the friction torque in a bearing is lowest with a quantity of the correct viscosity oil just sufficient to form a film over the contacting surfaces. grease should not be used. 4. 5. The correct amount of lubricant is not easily controlled as with oil. the thickener acts fundamentally as a carrier and not as a lubricant. and better sealing against dirt. Oil may flush debris out of the bearing. Greases are now used for lubricating by far the larger number of rolling bearings. Grease. 2. To lubricate the sliding contact between the rolls and guiding elements in roller bearings. When this unit is used the viscosities are quoted in terms of Saybolt Universal Seconds (SUS). During start-up periods. To protect the highly finished surfaces from corrosion. In a grease. piping is greatly reduced or eliminated. there are limitations which do not permit the use of grease. the time required for a fixed amount of oil to flow through a calibrated capillary is used as an intermediate value for calculating viscosity. it is a good rule to select an oil which will have a viscosity of at least 70 SUS (15 cSt) at operating temperature. 5. The friction will increase with greater quantity and/or high viscosity of the oil. A high viscosity oil will flow less readily than a thinner. formed by combining oil with soap or nonsoap thickeners. low viscosity oil. It is the relative resistance to flow. the bearing is instantly lubricated whereas with pressure or splash oil systems. 3. Listed below are some of the advantages and disadvantages of grease lubrication. 2. 283 . less maintenance. grease forms an effective collar at bearing edges to help seal against dirt and water. One of these is a function of the bearing design and the load imposed on the bearing. 2. Generally. The ability of any oil to meet the requirements of specific operating conditions depends upon certain physical and chemical properties. there can be a time interval during which the bearing may operate before oil flow reaches the bearing. Maintenance is greatly reduced since oil levels do not have to be maintained. and the speed of the bearing. Disadvantages Function of The Lubricant 1. is simply a means of effecting greater utilization of the oil. In the United States the instruments that are usually used are the Viscosimeter or the Viscometer. to carry away the heat developed in the bearing. In many cases. the friction torque will also increase with the speed. Grease will not. 1. associated machine elements that are oil lubricated dictate the use of oil for anti-friction bearings. 3. Lubrication Viscosity There are a number of instruments used for determining the viscosity of oil. the quantity. and whether oxidation inhibitors are used. is usually associated with good oxidation stability and can be used as a rough indication of such quality. It is for this reason that it is desirable that oil systems operate at as low an over-all temperature as is practical. Viscosity index is most important in an oil where it must be used over a wide range of temperatures. However. make-up is required only to replace that lost by vaporization. plug oil lines and cause corrosion. Pour Point Any oil. emulsification is undesirable and the oil should separate readily from any water present. In many instances. Some lubricating fluids are more resistant to this action than others. the contaminating particles act as agents to promote emulsification. they can not be depended upon to do an unfailing job of protecting rust-susceptible metallic surfaces. With any oil. and creepage from the bearing surfaces. In anti-friction bearing lubricating systems. Such oils are said to have a high viscosity index (V. Flash and Fire Point As an oil is heated. At temperatures below its pour point an oil will not feed into the bearing and lubricant starvation may result. however. Temperature is a primary accelerator of oxidation.I. sludge. Contaminants such as water and dust also act as catalysts to promote oxidation of the oil.I. Above this temperature. Although this small amount of oil can adequately lubricate a bearing. Rust is particularly undesirable in an anti-friction bearing because it can seriously abrade the bearing elements and areas that are pitted by rust will cause rough operation or failure of the bearing. The flash and fire points are significant indications of the tendency of an oil to volatilize at high operating temperatures. base oils of the same viscosity. There are many factors which contribute to the oxidation of oils and practically all of these are present in lubricating systems. and varnish residues which can reduce bearing clearances.I. the methods and° of refining used. water and straight oils do not mix. In selecting an oil for anti-friction bearings. This reaction results in the formation of acids. Once this small amount has been supplied. . fortify oxidation resistance. provide extreme pressure properties. Additives High grade lubricating fluids are formulated to contain small amounts of special chemical materials called additives. the lighter fractions tend to volatilize. Emulsification Generally. atomization.I. This is called the fire point of the oil.). heavily loaded bearings. These include temperature. The minimum quantity required is a film averaging only a few microinches in thickness. The oil should have good demulsibility characteristics. the pour point must be considered in relation to the operating temperature. eventually reaches a temperature below which it will no longer flow. Application of Lubrication Fluids The amount of oil needed to maintain a satisfactory lubricant film in an anti-friction bearing is extremely small. Additives are used to increase the viscosity index. and the effects of metals and various contaminants which increase the rate of oxidation. when cooled. base oils generally have higher flash and fire points than lower V. Some idea of the small quantity of oil required can be realized when it is known that 1/1000 of a drop of oil. Below 140˚F (60˚C). gum. or lower the pour point. A high V. High V. However. Oxidation resistance depends upon the fluid type. the rate of oxidation 284 increases to such an extent that it becomes an important factor in the life of the oil. some oils resist this change of viscosity more than others. increase film strength. This temperature is called the flash point of the oil. Rust Prevention Although straight petroleum oils have some rust protective properties. Such an oil should resist excessive changes in viscosity. having a viscosity of 300 SUS at 100˚F (38˚C) per hour can lubricate a 50 mm bore bearing running at 3. water can displace the oil from the surfaces and cause rusting. there is some temperature at which enough vapor is liberated to flash into momentary flame when ignition is applied. the rate of oxidation of oil is rather slow. improve rust protection. The oxidation rate of oil is accelerated by metals such as copper and copper-containing alloys and to a much lesser extent by steel.MRC Bearing Services Lubrication of Anti-Friction Bearings Viscosity Index All oils are more viscous when cold and become thinner when heated. agitation. At a somewhat higher temperature enough vapors are liberated to support continuous combustion.600 RPM. This temperature is said to be the pour point of the oil. much more oil is needed to dissipate heat generated in high speed. when an oil becomes dirty. Oxidation Resistance All petroleum oils are subject to oxidation by chemical reaction with oxygen of air. It is well known that rates of chemical reaction double for every 18˚F (10˚C) increase in temperature. provide detergent properties. i.

If necessary. oil jet. an improvement in bearing performance (life) can be expected.Lubrication of Anti-Friction Bearings Oil may be supplied to anti-friction bearings in a number of ways. Approximate equivalent SAE viscosity grades are shown in parentheses. however.5 (45 + 85) = 65 mm. It decreases with increasing temperature. varies with temperature. a lubricant of at least 46 mm 2 /s viscosity at the standard reference temperature of 40˚C. assuming that the temperature of the bearing housing is 77˚C (170˚F).)/2 v1 = required lubricant viscosity for adequate lubrication at the operating temperature 285 . varies with bearing design. and splash or spray from a slinger or nearby machine parts. the intersection of dm = 65 mm with the oblique line representing 2000 rpm yields a minimum viscosity required of 13 mm 2 /s. Therefore.5 (d + D) = 0. These include bath oiling. rather than the viscosity grade (VG) which is based on the viscosity at the internationally standardized reference temperature of 40˚C (104˚F). it should be kept in mind that the temperature of the oil is usually 3˚ to 11˚C (5˚ to 20˚F) higher than that of the bearing housing. wick feed. Figure 1 yields the minimum required viscosity as a function of bearing size and rotational speed. the temperature of the oil will usually be 80˚ to 88˚C (176˚ to 190˚F). however. Where cooling is required in high speed and heavily loaded bearings. One of the simplest methods of oil lubrication is to provide a bath of oil through which the rolling element will pass during a portion of each revolution. Now let us assume that the operating temperature is 80˚C (176˚F). If a lubricant with higher than required viscosity is selected. the intersection between temperature 80˚C and required viscosity 13 mm 2 /s is between the oblique lines for VG46 and VG68. Therefore. The viscosity of a lubricating oil. When determining the operating temperature. oil jets and circulating systems should be considered. the viscosity at the operating temperature must be used.D. The pitch diameter dm = 0. Example: A bearing having a bore diameter of 45 mm and an outside diameter of 85 mm is required to operate at a speed of 2000 rpm. which. Figure 2 can be used to determine the actual viscosity at the operating temperature. Figure 1 Minimum Required Lubricant Viscosity dm = (bearing bore + bearing O.e. As shown in Figure 1. the oil can be passed through a heat exchanger before returning to the bearing. circulating system. a lubricant with the viscosity grade of at least VG46 should be used. For instance tapered and spherical roller bearings usually have a higher operating temperature than ball bearings or cylindrical roller bearings under comparable operating conditions. Figures 1 and 2 should be used to assure that the viscosity is adequate in an application. In Figure 2. Selection of Oil The most important property of lubricating oil is the viscosity. For example. drip feed. oil mist from an external supply. . Therefore the lubricant flow rate through the bearing should be as little as possible. or polyphenyl ethers instead of petroleum oil. rust prevention. Sometimes a mixture of soaps is used to alter the properties. It is recommended that the bearing user consult with MRC Technical Services Department to determine the lubricant which will be most suitable for the application. they have excellent rust preventive properties due to their ability to absorb minor amounts of water contamination.0020 0. and oxidation stability. since increased viscosity raises the bearing operating temperature. Greases containing thickeners other than metallic soaps are being used increasingly because they offer greater resistance to heat. This minimum acceptable flow rate can be achieved using air-oil mist lubrication. consideration must be given to the choice of a grease. Synthetic greases are used in extremely high or low temperature applications that are outside the range for petroleum greases. consistent with good lubricant film formation and heat removal. In the great majority of applications where the operating conditions are normal. Lithium soap petroleum greases are widely used because of their good water resistance. insufficient lubricant enters the rolling element-raceway contacts to permit formation of lubricant films thick enough to separate the components. excessive quantity of lubricant within the bearing boundary dimensions. melting point. However. causes increased friction and hence increased heat generation owing to fluid churning. many different greases can be used satisfactorily. The thickener may be soap or non-soap.e.0015 0. grease lubrication can now be achieved over a temperature range of –100˚F to + 500˚F (–73˚C to 260˚C) and higher in some cases. However. The type and quality of soap determines the grease consistency. dm is bearing pitch diameter in inches.Lubrication of Anti-Friction Bearings However. the viscosity should be expressed in mm2 /s (cSt) rather than in Saybolt Universal Seconds (SUS). Sodium soap greases are not water resistant and are readily washed away by large amounts of water. Soap is formed by combining a metallic alkali such as the hydroxide of sodium or lithium with a fatty material. and good mechanical stability. In applications where elevated temperature. For comparative viscosity classifications and conversion tables see next page. Additives are used to impart such properties as increase in load carrying capacity.

Care must be exercised to assure that the lubricant flow rate is sufficient to avoid lubricant starvation in high speed applications. heavy loading. and solubility in water. Intensive research in the development of oxidation resistant formulations has resulted in great increases in the life which lubricating greases can provide. the SUS scale shown on the right of Figures 1 and 2 can be used for approximate conversion of SUS to mm2 2 /s (cSt).

Most rolling bearing greases fall into classes 1-4. which is accelerated with higher temperatures. In this test. The Shell Roll Test subjects the grease to the working action of a roll inside a rotating cylinder. The dropping point cannot be used to indicate the maximum operating temperature for a grease since some greases oxidize or decompose rapidly at temperatures below the dropping point. Even those classed as water insoluble or water resistant can be washed out of a bearing if exposed to large volumes of water. The 60 stroke working is done to minimize the effects of any previous manipulation of the grease in sampling. Other types are less affected but their resistance to washout varies with the viscosity of the oil and the amount and type of thickener. However. No lubricating grease is completely water resistant. Penetration values are determined before and after rolling. Listed in the table below is a classification of the consistency of grease in terms of worked penetration as developed by the National Lubricating Grease Institute. However. described earlier under Consistency. Also. this working cannot be correlated to the much more severe shearing action that occurs in a bearing. After one hour of operation at 600 RPM with the water at a controlled temperature impinging on the housing at a specified rate. established by the American Society for Testing and Materials. forces the grease through a perforated plate at a rate of 60 times per minute. the rate of absorption of oxygen by the grease at 210˚F (99˚C) and 110 PSI is recorded. Dropping Point When a grease is heated. it softens. depressions in the grease surface or voids collect oil. Most sodium soap greases emulsify and thin out when mixed with water. By far the greater portion of bearing applications use NLGI Grade 2 grease. uses a penetrometer with which a cone of standard shape and weight is dropped into the grease and the depth of penetration in five seconds at 77˚F (25˚C) is measured in tenths of a mm. Usually greases become softer when subjected to mechanical working action. the worked penetration indicates the relative softening after a limited amount of shear. Dropping point is of little significance to the grease user but it is of significant value to the grease maker as means of quality control. Two grease working tests are used to measure softening of grease due to working. Water Resistance Water resistance varies with the different types of greases. This reaction ultimately results in drying and hardening of the grease with total loss of lubricating properties. The° of softening that results from working is important from the aspect of leakage from the bearing. The temperature at which a drop falls from a sample in a standard test (ASTM D-566) is called its dropping point. brick type greases which are cut with a knife. is one of the main factors 288 The standard test used to measure the oxidation stability of grease is the Oxygen Bomb Method (ASTM D-942). The penetration is usually measured on both unworked grease as it comes from its shipping container and also after it has been worked 60 strokes by a perforated disc plunger. Consistency Greases vary in consistency from semi-fluids to hard. NLGI No. Oil Separation Most greases show some tendency to allow oil separation in certain circumstances. However.MRC Bearing Services Lubrication of Anti-Friction Bearings Grease Characteristics limiting the life of bearing greases. the results cannot be correlated to bearing performance since greases which have appeared unsatisfactory in these tests have been found to provide very satisfactory bearing performance. 1 2 3 310 – 340 265 – 295 220 – 250 Shear Stability (Mechanical Stability) 4 5 6 175 – 205 130 – 160 85 – 115 This is the resistance of a grease to structural breakdown when subjected to the shearing action of being worked.

A ball bearing with a specified quantity of the test grease is mounted in a housing with specified clearances to allow entry of water from a jet. The method for measuring grease consistency (ASTM D217). These consistency measurements are expressed as unworked and worked. it has been found that greases which show low oxygen absorption usually perform reasonably well in service. the bearing is reweighed and the amount of grease lost is determined. Oxidation Stability Reaction with oxygen in the air. During storage. This test is conducted under static conditions and is intended only to be useful in estimating the shelf life of greases. Channeling type greases are usually of NLGI No. greases thin out at high temperatures. Channeling Channeling is a term referring to the tendency of a grease to separate and form a channel after the passage of the balls and cage around the ball race. petroleum oils tend to oxidize rapidly and sometimes it becomes necessary to use special petroleum oils or synthetic oils to increase the service life of the lubricant. Generally. operating at cold temperatures. 4 consistency. Starting torque is not a function of the consistency or the channeling properties of a grease. For oil lubricated bearings High Temperature In oil lubricated bearing applications where ambient temperatures are high. the maximum temperature at which a grease will provide a reasonable life in a non-relubricable bearing. Usually the separated oil can be easily stirred back into the grease body. 3. oil cooling tanks. The high temperature limit for greases. i. cooling discs. Resistance to the effects of nuclear radiation. a correctly selected grease provides lower torque than an oil. Special Properties There are many special grease formulations to meet a variety of unusual requirements. It appears to be a function of the individual properties of the grease and is difficult to measure. and fans. Poor channeling characteristics can make some greases unsatisfactory for high speed operation when a channeling type grease will provide minimum torque and heat rise. temperature rise can usually be held to a reasonable level by the use of a suitable lubricant in proper quantity. As mentioned earlier. The test is conducted at 77˚F (25˚C) and after 24 hours the separated oil that has collected on the bottom of the cell is weighed and expressed as a percentage by weight of the original sample. The rate of oxidation of lubricating fluids increases rapidly with temperature rise. 9. 8. 4. Some of the commonly used methods for decreasing the oil temperature are cooling coils. some means of cooling is usually necessary to avoid excessive bearing temperatures and premature lubricant failure.5% for machined land guided cages Operating Conditions Low Temperature Oils and greases tend to thicken and resist flow as temperatures are decreased. Where the only heat is that generated by the bearing. such as in ovens. a high viscosity index is desirable. Usually the most important consideration in selecting a grease for low temperature operation is start-up torque. an oil that has a sufficiently low pour point to remain fluid at the low temperature and the proper viscosity for the operating temperature should be chosen. High Speeds Small size anti-friction bearings are often successfully grease lubricated at high speeds.

It is sometimes seen in the bearings of idle machinery that has been subjected to the vibrations of nearby machines.Where wet conditions are so severe that satisfactory protection cannot be provided by a lubricant. Extreme Pressures Various extreme pressure agents are compounded into some greases and oils. This effect evidences itself by the formation of rust-like wear debris and the formation of wear spots. Fretting Anti-friction bearings are sometimes damaged by a wear effect that is variously called fretting corrosion. Even slight corrosion on the internal surfaces may initiate bearing failure. Ball and roller bearings are. However. or oscillation of small amplitudes. the bearing may become corroded. higher viscosity oils are required to prevent metal to metal contact if pressures are higher than normal or if shock loading occurs. Water soluble sodium base greases will form a noncorrosive emulsion when mixed with a limited quantity of water. it is good general practice to use a soft grease such as an NLGI 0 or 1 grade or a harder grease which tends to soften considerably upon working. . If water should enter an idle bearing. Where the bearings operate in dusty or dirty atmosphere the grease should be chosen with its sealing properties in mind. and chlorine compounds. the wear in these contact areas will become so extensive as to prevent functioning of the bearings. There is a limit to the amount of water which a water soluble grease can absorb and still protect the bearing surfaces. Fretting can be eliminated or minimized by the selection of a lubricant which has good feed ability. agitation is necessary to form this emulsion. the selection of oil viscosity must be a compromise between a heavy oil which is desirable for heavy loading and a light oil which is desirable for high speeds. 290 Slow moving bearings can be packed full of a cohesive. Oil lubricated bearings are generally protected from foreign particle contamination by the use of oil filters and the properly designed seals required in oil lubricated systems. Dust and Dirt A high percentage of ball and roller bearing troubles can be attributed to foreign matter entering the bearing after mounting. These include additives such as sulfur. graphite. Usually. Wet Conditions Whenever possible. However. an anti-friction bearing should be protected from water and moisture to avoid corrosion. Because anti-friction bearings are highly sensitive to dust and dirt. The quantity of oil needed for successful operation becomes greater with increasing temperature. Fretting can occur in bearings subjected to vibration. With grease lubrication in applications where fretting is a problem. the stiff consistency of an NLGI Grade 3 grease will provide a good sealing barrier. it is sometimes necessary to use bearings fabricated of special corrosion resistant alloys or bearings with corrosion resistant coatings. such additives are generally not required in anti-friction bearing lubricants and should be avoided unless their use is dictated by other associated equipment such as gears. For small and medium size bearings rotating at high speeds. For most applications. If allowed to progress. vibratory loads. The term ‘‘water resistant grease’’ is actually a misnomer since no grease will totally resist large amounts of water for extended periods. With other influences being equal. elaborate protective devices are necessary in some applications. Grease in sealed and shielded bearings can provide an effective barrier against dust and dirt. drip feed or oil mist is satisfactory. and bearing size. In cases where heavily loaded bearings operate at high speeds. Lubrication of Anti-Friction Bearings The temperature range over which a grease can be used depends on the type of base oil and thickener used as well as the additives. size. is determined by the base oil and its viscosity. It should be remembered that a grease will age (deteriorate) and oxidize with increasing rapidity as the temperature increases and that oxidation products have a detrimental effect on lubrication. etc. the relubrication interval is often longer than the life of the bearing application.5 4 3.5 50 10 2 10 2 3 4 5 6 7 8 9 10 3 2 3 4 5 6 7 8 9 10 4 2 n r/ min Scale a: radial and angular contact ball bearings Scale b: cylindrical roller bearings.

A more preferable method of removing entrapped water after draining is to spin the bearings in a water displacing type rust preventive oil. most of the oil is lost.e. A stiff brush may be used to dislodge solid particles. The same practice also applies to oil jet lubrication. preferably overnight or longer. e. Bearings which are satisfactory for further service should be immediately rotated in light oil to displace the solvent. 292 Bearing Cleaning New bearings should be cleaned only if they have been exposed to dirt after removal from their package or lubricated with an oil or grease that is incompatible with the preservative. Relubrication The amount of grease needed for relubrication can be obtained from Gp = 0. A light hand thrust should be applied against one bearing ring while slowly rotating the other ring. A grease gun (lubricator) can then be used. the bearings should be immersed in solvent for cleaning.005 D B where Gp = grease quantity. After a number of such relubrications the housing should be opened and the used grease removed before fresh grease is added. boiling in emulsified cleaners (i. After removing the water. The use of compressed air for blowing dirt out of bearings and drying solvents is not recommended unless the air system is filtered to remove moisture and dirt. their condition may be judged by hand. fresh grease should first be packed between the rolling elements. preferably a grease nipple should be fitted to the housing. spindle oils. This reduction also applies to applications where the grease is required to seal against moisture. Those which will not be installed immediately should be coated with a good rust preventive oil and wrapped in clean oilproof paper. Light transformer oils. Where more frequent relubrication is required provision should be made for regreasing. Cleaning Unmounted Used Bearings Place bearings in a wire or mesh basket and suspend the basket in a suitable container of clean petroleum solvent or kerosene.g. Where oil bath lubrication is employed it is normally sufficient to change the oil once a year. Bearings should never be spun at high speed by a stream of compressed air during cleaning as this may cause damage to the balls and raceways. . or floor cleaning compounds) may be more effective to soften hard deposits. (See Compatibility of Lubricants. For circulating oil systems the period between complete oil changes is dependent on how often the oil is circulated over a given period of time and whether it is cooled. This may be accomplished by draining and slowly rotating the individual bearings while hot until the water has been completely evaporated. g D = bearing outside diameter. grinding. If hot emulsion solutions have been used. cutting. Relubrication Intervals—Oil The frequency at which the oil must be changed is mainly dependent on the operating conditions and on the quantity of oil used. it is important that all entrapped water be removed from the bearings. To ensure that fresh grease actually reaches the bearing and replaces the old grease. it is sufficient if the bearing housing is accessible and can be opened easily. After the used bearings have been thoroughly cleaned. 294). as it is conveyed to the bearing only once. at a temperature of 100˚C (220˚F) the oil should be changed every 3 months. mm B = total bearing width.

The cap of split housings and the cover of onepiece housings can usually be taken off to expose the bearing. provided the bearing temperature does not exceed 50˚C (120˚F) and there is no contamination. should be relubricated once a week. The most suitable period can generally only be determined by trial runs and frequent examination of the oil. the lubrication duct in the housing should either feed the grease adjacent to the outer ring side face. The loss of internal clearance can result in premature bearing failures due to a significant increase in ball and race stresses. the bearings should be operated for about ten minutes before the vent plugs are replaced to avoid serious over-heating of the bearing due to churning of excess grease. This precaution is especially important when there is a close running clearance between the separator and one of the rings. the bag can be inserted between the separator and either ring. knife-like blade between the O. Usually the seal can be removed without damage. very efficiently dissipate heat from the housing and outer ring of the bearing. After purging with grease. however.Lubrication of Anti-Friction Bearings Cleaning Mounted Used Bearings For cleaning bearings without removing them from their mounted assembly. It is important to work around the periphery rather than exert too much pressure at one point which may damage the seal. The preservative is compatible with petroleum base oils and lubricants. Synthetic hydrocarbons are an exception. It is recommended that the preservative be removed from the bearing surfaces before lubricating with either of these products. Things You Should Know About Lubrication MRC bearings that have seals or shields are generally lubricated for the life of the bearing. Bearings having two shields that are held in place by snap rings can be cleaned and regreased by carefully removing the shields and reinstalling them. This may be done. Because machined phenolic or metal separators occupy a considerable amount of the space between the bore of the outer ring and the OD of the inner ring in a bearing. One method of introducing grease between the rings and the separator is to use a plastic bag. In applications where either water or air is used to dissipate heat from the bearing cavity. special care must be exercised when introducing grease into these bearings to ensure that it is uniformly distributed in the bearing. The shaft should be rotated slowly throughout these operations.e. Synthetic oils and greases compounded with synthetic oils are classified as special condition lubricants. Operation of the bearing will eventually uniformly distribute the grease. Some cooling methods. Grease can then be forced into the bearing by squeezing it from the bag. light oil at 180˚F (82˚C) may be flushed through the housing while the shaft or spindle is slowly rotated. It is possible that either synthetic oil or greases compounded with synthetic oils. It is also possible that greases compounded with a polyurea thickener may cause excessive grease softening due to incompatibility with a petroleum base preservative. new grease may be forced through the bearing to purge the old grease and contaminates. light oil. but have little effect on the shaft and bearing inner ring. hot. The best procedure for removing the seal is to insert a thin. an intermediate flushing with a mixture of alcohol and light petroleum solvent after the emulsion treatment may be helpful. They are usually not the best choice for operating conditions that fall within the capability of petroleum base lubricants. but it is possible to initiate a heating-type failure or to cause damage to the active surfaces in the bearing before this occurs. If grease is sealed in a plastic bag and a small opening is cut across one of the corners. working the seal from the groove. In cases of badly oxidized grease and oil. internal clearance in the bearing is removed as the result of thermal expansion of the inner ring and thermal contraction of the outer ring. only if contamination is not severe and vent openings are provided in the housing for exhausting the old grease. Bearings having one seal or one shield may be cleaned satisfactorily by the methods outlined here. hot water emulsions can be used in place of flushing oil. These bearings are normally inspected and reused or rejected on the basis of smoothness and looseness. The solution should be drained thoroughly and the housing flushed with hot. i. The flushing oil should be drained completely and oil passages checked to make sure they are not clogged before adding new lubricant. Cleaning Sealed or Shielded Used Bearings Bearings which have non-removable double shields or seals cannot be cleaned. In some cases where deposits are extremely difficult to remove. then slowly work around the periphery of the seal. will not be compatible with a petroleum base preservative. water jacketed housings. Under these conditions. One way to avoid this problem is to circulate and cool the oil. of the seal and the seal groove in the outer ring. If the bearing is lubricated with grease. 293 .D. and also due to excessive heat generation. care must be exercised not to create a significant temperature differential between the bearing inner ring and outer ring. It is not necessary to remove the preservative from the bearing surfaces when the bearing will be lubricated with either a petroleum base oil or grease. Bearings that do not have seals or shields are protected from corrosion by coating the bearing with a preservative. Synthetic hydrocarbon may be an exception. Bearings having two removable rubber seals can be cleaned and regreased if care is exercised in removing and reinstalling the seals. They are expensive and lack some of the desirable lubricating qualities of petroleum base lubricants. the oil can be passed through a heat exchanger before returning to the bearing. . bearings should be stored at a temperature not greater than 80˚F (27˚C) and at a humidity not exceeding 55 percent. Entry and exit of the oil should be on opposite sides of the bearing. introduced through a filter-type. Lubrication Methods Figure 2 Drip Feed Lubrication This system is widely used for small and medium ball and roller bearings operating at moderate to high speeds where extensive cooling is not required. The oil. not to mix different types of greases or oils. Figure 2 illustrates a typical design and shows the preferred location of the oiler with respect to the bearings. The mixing of the same type of grease or oil from two different manufacturers can also cause a performance loss unless the manufacturers use the same additives. Systems of this type generally employ sight gages to facilitate inspection of the oil level. Incompatibility results when the mixture is too soft or too stiff to effectively lubricate the bearing. sight feed oiler. The shelf life of the grease or preservative can be significantly shortened if bearings are stored in an unsatisfactory environment. has a controllable flow rate which is determined by the operating temperature of the bearings. Also. A greater amount of oil can cause churning which results in abnormally high operating temperatures. It is also desirable to select an area where there is not a great fluctuation in temperature that might produce condensation.Lubrication of Anti-Friction Bearings MRC Bearing Services Compatibility and Storage It is important when relubricating bearings. If necessary. in order to reduce the likelihood of bearings being held in storage for excessively long periods of time. Figure 1 Oil Bath Lubrication A simple oil bath method is satisfactory for low and moderate speeds. An adequate drainage system must be provided to prevent an excess accumulation of oil. bearing stocks should be rotated to make certain that the oldest bearings in stock are used first. Mixing greases often causes the mixture to become either softer or stiffer. The static oil level should not exceed the center line of the lowermost ball or roller. 294 Figure 3 Forced Feed Circulation This type of system uses a circulating pump and is particularly suitable for low to moderate speed. Figure 1 shows a constant level arrangement for maintaining the correct oil level. Because both temperature and humidity accelerate the deterioration of either grease or a preservative. Oil filters and magnetic drain plugs should be used to minimize contamination. There are several environmental considerations when selecting an area for storing bearings. heavily loaded applications where the oil has a major function as a coolant in addition to lubrication. See Figure 6. high speed bearings operating at high temperatures. A rule of thumb on the use of oil mist is obtained from the formula K <109. This method insures positive entrance of oil into the bearing to provide lubrication and cooling of the inner ring. K = DNL. oil feeder trails should be designed into the gear case to direct oil into the bearings. N = inner ring speed RPM.D. Figure 4 At extremely high speeds. Figure 6 Oil Splash Lubrication This method of lubrication is used mainly in gear boxes where the gear oil splash is used to lubricate the bearings. In applications where the oil splash is heavy. scavenging may be required on both sides of the bearing.Lubrication of Anti-Friction Bearings In applications of large. the bearing tends to reject the entry of sufficient oil to provide adequate cooling and lubrication with conventional oil jet and flood systems. D = bearing bore in mm. Attention must be given to wicks to assure that they are not clogged and they must be replaced occasionally. In applications where normal splash does not provide adequate lubrication. Bearings are constantly fed with an optimum quantity of oil thus minimizing bearing heating due to oil churning. In mist lubrication systems. Systems can be designed so that a positive pressure is maintained within the housing thereby preventing the entrance of contaminates. Figure 4 shows an under-race lubrication system with a 9000 series bearing having a split inner ring with oil slots. In such cases the use of several jets on both sides of the bearing provides more uniform cooling and minimizes the danger of complete lubrication loss from plugging. 295 . it may be necessary to use high velocity oil jets. see Figure 7. the oil is atomized and transported in an airstream through tubing to the bearings. mist lubrication does provide some cooling from the continuous forced circulation of air. While not as effective as flood lubrication for heat removal.. are usually reserved for high speed applications. Wick feed is satisfactory for high speed operation with no danger of excessive oil churning. shielded bearings are sometimes used to reduce the amount of oil reaching the bearing to prevent heating from excessive churning. Figure 7 Oil Mist Lubrication Figure 5 Wick Feed Lubrication Wick oilers function either by gravity or capillary action to transfer a small quantity of filtered oil from a reservoir to the bearing. Adequate scavenging drains must be provided to prevent churning of excess oil after the oil has passed through the bearing. Oil mist systems. In special cases. heavily loaded. The jet stream should be directed at the opening between the cage bore and inner ring O. L = load in pounds. see Figure 3. Figure 5 shows an arrangement whereby the wick conveys oil by capillary action to a rotating flinger where it is thrown off by centrifugal force and drains back through the bearing. or a separate plate.Lubrication of Anti-Friction Bearings MRC Bearing Services Figure 10 Deep Groove Ball Bearings on Vertical Shaft In vertical applications where grease is admitted above the bearing. Note that ample grease space has been provided and that the configuration of parts adjacent to the bearing is such as to urge the lubricant into contact with the active bearing parts. The direction of flow tends to remove the old grease. The grease plug at the bottom should be removed while the grease is being inserted through the fitting at the top. as shown in figure 10. Where prelubricated sealed bearings are not suitable for some reason. consideration must be given to use of an open type bearing with provision for relubrication. Figure 9 High Temperature Grease Mounting The life of permanently lubricated installations at high temperatures is a function of the volume of grease present and the design of the mounting. Figure 8 Regreaseable Mounting Recommended for moderate speeds and loads. 296 . the bearing should be provided with a shield on the lower side. to retain the grease. thus allowing grease to be applied to both bearings.

Removable Sleeves and Removal Nuts Removable sleeves have a taper on the outside diameter corresponding to the taper in the bore of the bearings. The locknuts are accurately made to insure that the abutment face will be square with the shaft axis. A removal nut is used to remove the sleeve from the bearing. It permits relatively wide tolerances for the shaft diameter and makes it unnecessary to heat the bearing or use a press when mounting in order to obtain an interference fit of the inner race on the shaft. These sleeves are used for applications where bearings must be removed occasionally for the inspection of machine parts and at the same time will be positively located on the shaft with the equivalent of a press fit. use locknuts. lockwashers and lockplates. Wherever bearings must be held in permanent or correct position. The lockwashers are made from selected high quality steel. In assembling. the sleeve is locked on a threaded shaft by means of locknuts. Adapters The adapter is used to hold and locate a tapered bore bearing on a cylindrical seat. The lockplate is a steel stamping that engages the slot of the sleeve and is secured to the end face of larger nuts by two screws. Adapters are manufactured with the same precise techniques and care used in the manufacture of bearings.Bearing Accessories Locknuts. They are also frequently used to secure gears. and they must pass a final inspection that requires their finish to be smooth and free from burrs. thus avoiding distortion of the shaft during tightening. This unit is used in place of lockwashers. belt pulleys and other machine components. lockwashers and lockplates. Lockwashers and Lockplates Locknuts and lockwashers are commonly used as effective means for holding bearing inner rings axially on the shaft. heat treated. 325 . 8740 8.1811 1.281 W03 W04 W05 1.000 W06 W07 W08 1.0 .510 57.7 1¹|₈ 1³|₈ 1⁹|₁₆ 8.041 1.398 7.60 .07 1.050 38.313 W12 W13 W14 1.1 .531 7.83 1.5 97.438 8.4 .1496 3.96 3.18 3.656 W09 W10 W11 1.001 90.7 19.7 4.5 5.396 .365 .104 187.1181 5.Locknuts & Lockwashers for Ball Bearings ABMA Standards MRC Bearing Services Locknut Lock Nut No.4 3.4 1.042 .9055 171.480 1.354 .3937 .918 1.3 68.1654 64.0 N12 N13 N14 60 65 70 2.6 6.428 .

With non-separable bearings. the materials from which the shaft and housing are fabricated and the distance between the two bearings. the bearing must be turned over a number of times. With separable bearings. Bearings are placed so that the unmarked (low shoulder side) of the outer rings are together. cylindrical roller bearings and tapered roller bearings are designed as separable bearings. If hotplates are used. particularly where each ring is to have an interference fit. 150˚C [300˚F ] should not be heated to more than 125˚C [250˚F ] since dimensional changes caused by alterations in the material structure may occur. The required difference in temperature between the bearing ring and shaft or housing depends on the° of interference and the diameter of the bearing seating. care must be taken that the shaft is correctly aligned with the housing to prevent scoring the raceways and damaging the rolling elements. In the case of split inner ring ball bearings and cylindrical roller bearings. Local overheating must be avoided when heating bearings. Uniform. It is generally not possible to mount larger bearings in the cold state. or other steels suitable for normal operating temperatures (for example. as the force required to mount a bearing increases very considerably with bearing size.

The inner rings of medium and large cylindrical roller bearings which have no flange or an integral flange on one side only may be heated using an induction heating tool or heating ring. Guideline values for the temperature differences required for some of the most commonly employed fits of bearings may be found in the accompanying diagram (Figure 3). 205˚C [400˚F ] for mounting purposes. the inner ring can be mounted independently of the outer ring. the inner rings or the housings are heated prior to mounting. when one bearing is adjusted against a second bearing. differential thermal expansion will cause a reduction in clearance. 330 The appropriate value for the clearance to be obtained when mounting is determined by the conditions when the bearing is under load and at the operating temperature. the initial clearance must be sufficiently large so that distortion of the bearings and resultant detrimental effects are avoided. For a cylindrical roller bearing. This simplifies mounting. Temperature Difference ˚C Bearings fabricated from steels capable of operation at higher temperatures may be heated to somewhat higher temperatures.g. the initial clearance obtained on mounting may be smaller or larger in actual operation.. this means that the outer ring. damage may easily be caused to the rings or rollers especially if the rollers and raceways are not oiled or if the parts are rotated during fitting. cage and rolling elements comprise a non-separable unit when the inner ring is removed. Contact angle lines of the bearings converge outwardly. Ready-greased bearings fitted with seals and/or shields should not be heated. with the inner ring already mounted. risk-free heating can be achieved using induction heaters. If. Face-to-face Bearings are placed so that the marked backs (full shoulder side) of the outer rings are together. away from the bearing bores. Sometimes the inner ring. electric heaters. . this is usually the case for tapered roller bearings. Contact angle lines of two bearings converge inwardly toward the bore of the bearing. in contrast to other radial bearings. should either part of the bearing be mounted askew. The bearings. Depending on the size and arrangement of the bearings. cage and rolling elements comprise the non-separable unit. Usually these bearings are arranged in face-to-face or back-to-back pairs. Bearing Adjustment The internal clearance of single row. and one bearing ring is axially displaced until a given clearance or preload is attained (Figure 4). angular contact ball bearings is only established. into the housing containing the outer ring. for example. when designing the bearing arrangement. Figure 6 Bearing Ring Puller Small bearings may be removed from their seatings by using a puller as illustrated in Figure 5. e. The actual methods used to adjust the clearance and measure the set clearance are determined by whether a few or many bearings are to be mounted. the ring with the rolling element and cage assembly can be removed independently of the other ring.. the ring having the looser fit should be removed from its seating first. With non-separable bearings. Dismounting of Bearings If bearings are to be reused after removal from the application. With separable bearings.g. the tools and accessories described in the following may be used depending on bearing type and size. The claws of the puller should be placed against the side face of the ring to be removed or an adjacent component. generally the axial internal clearance. the force used to dismount them must never be applied through the rolling elements. etc. or by inserting calibrated shims between one of the bearing rings and its abutment. starting from a condition of zero clearance. it is sufficient to specify a single value. slots are provided in the shaft and housing shoulders to accommodate the claws of the puller. To dismount a bearing ring having an interference fit. a labyrinth ring. Outer rings can be removed more easily from their housings if tapped holes are provided in the shoulders to take withdrawal screws (Figure 6).Installation Procedures Since there is a definite relationship between radial and axial internal clearance of angular contact ball bearings. by loosening or tightening a nut on the shaft or a threaded ring in the housing bore. Figure 5 331 . Dismounting is made easier if. This specified value is then obtained. Use of a snap-ring bearing (as shown on the left) makes use of a through bore housing possible. together with the spacer which separates them.) This construction has the same advantages as those enumerated above. yet small enough to eliminate excessive chucking under reversing thrust load. These shims are usually mounted between the face of the bearing outer ring and the end cover shoulder. Note that the inner rings of both bearings. This means of mounting may be effectively employed where there is no rapid alternation in the direction of the thrust load. It permits one bearing to take thrust in either direction. This type of mounting differs from that shown in the top sketch on the opposite page in that the bearing on the right end is held on the shaft by a snap-ring which eliminates the lock nut and the necessity of threading the shaft. Axial shaft expansion is provided for by the ‘‘floating’’ of the unclamped bearing. The lock nuts serve to clamp the bearing inner rings against the shaft shoulder. 2. This mounting arrangement is suitable for a wide range of speed and temperature conditions. The bearings cannot be axially preloaded through improper adjustment of the lock nuts. 3. are clamped against the shaft shoulder by means of one lock nut at the end of the shaft. Due to tolerance build-up of the various components.Installation Procedures MRC Bearing Services Typical Horizontal Mountings For Single-Row Radial and Double-Row Bearings This is the ideal mounting for a shaft supported by two ball bearings. it is difficult to control the axial play of the shaft unless shims are used. and has these advantages: 1. thereby allowing economies in manufacture. and should be used where the bearings are assembled from one end of the shaft. Axial play of the shaft should be sufficiently large to eliminate any possibility of preloading due to thermal expansions. (Compare mounting above which requires two lock nuts. 4. It is also adaptable for locations where shaft length is short. 332 The mounting shown above employs no lock nuts on the shaft and permits through bore in the housing. . This is an alternate mounting with that shown above. if desired. Adjustment is made by means of the lock nut. and where thrust is not excessive. 333 . be taken care of by a smaller angular-contact bearing. or by a radial bearing. with shim adjustment. This construction requires housing shoulders. This eliminates shaft end play and enhances quiet bearing operation. Owing to the difficulty of accurate adjustment and danger of excessive tightening. Lock nuts on the shaft can in general be dispensed with. The commercially available spring washer provides a small preload to the bearings. This construction requires a shoulder on the shaft. and a lock nut on the shaft. Also the reverse thrust can. Pair of Angular-Contact bearings mounted opposed to take thrust in either direction. If the thrust in one direction is substantially less than in the opposite direction. the bearings can be of different sizes so as to give approximately equal safety factors. this mounting is not often recommended. but should be used where the inner ring must be very firmly secured to resist shock or vibratory loads.Installation Procedures The above mounting can be used where both shaft and housing have shoulders. and a clamping member of the outer ring. The left hand bearing should have a sliding fit on the shaft. Oil flow into the chamber below the bearings is adjusted by means of a metering pin. This system has a unique advantage in that the bearings may be completely covered by the oil level during shut-down. The 9000-UD bearing may be mounted above (as shown) or below. The sketches below show three approved mounting arrangements. thereby protecting them against damage through corrosion. If reversing thrust is present. The radial support bearing at the bottom of the shaft need not be shimmed to carry the up-thrust.Installation Procedures MRC Bearing Services Typical Vertical Mountings For Angular-Contact Bearings Vertical mountings are frequently used with oil lubrication. . but maintaining the same orientation of bearing faces. This requires a means for lifting the oil into contact with the bearings. 334 Application of MRC 97000 Series The bearing arrangement above is capable of supporting extremely heavy thrust in the downward direction as well as substantially heavy thrust loads in the upward direction. From this point the oil returns by gravity to the reservoir shown at the left. The design above is suited for uni-directional thrust. (See page 237) In the lubricating arrangement shown. Note that the oil is lifted into the bearing by means of the inverted rotating cone. The sketch above shows the conventional method of circulating oil in a vertical application. it must be taken by an opposed bearing mounted at the bottom of the shaft. Reverse thrust loads must be carried by an opposed bearing. Note that the dish-shaped oil thrower pumps the oil up through the drilled hole in the housing from which the oil flows downward through the bearing by gravity. the 7000-D. Attention is called to the drilled hole which prevents possible siphoning out of the oil when the shaft is stationary. the bearings serve as a pump to elevate the oil from the chamber immediately below the bearings to a passageway at the top of the bearings. In this arrangement the shaft is supported at the right end by a duplex pair mounted in the back-to-back relationship. The duplex back-to-back pair on the left end of the shaft is free to move axially in the housing. The pairs at either end are separated by equal length spacers between bearing outer rings and inner rings. This not only lubricates the bearings. 335 . Additional sealing protection is often provided by introducing airoil mist in the chamber between the two bearings. the floating bearing is sometimes mounted in a cartridge in order to improve the length-to-diameter ratio of the sliding member.080mm) to ¹|₁₆˝ (1. This arrangement produces good shaft rigidity due to the multiple shaft support. The shaft is located axially by the arrangement on the right end of the shaft which consists of a pair of tandem bearings opposed back-to-back against a single bearing.59mm). but also assures a positive outward flow of air through the labyrinth passage. This is the simplest high speed mounting arrangement and is used for a wide variety of applications involving extremely high speeds. The radial clearances in the labyrinth should be . This mounting arrangement has great rigidity. For extremely high speeds. primarily for machine tool spindles.25mm) and the axial clearances should be approximately ¹|₃₂˝ (. In this arrangement. Bearing on left end of shaft must be free to float in housing for preload to be effective. Note the rugged sections for minimizing deflection and the labyrinth flinger seals for protecting the bearings against the entrance of foreign material. The spring pack bears against the face of the outer ring on the bearing at the left in order to preload the two bearings.

The power is generally transmitted to another shaft by means of gears. lbs. lbs. 1 shows a gear train. so that if the torque of the driving shaft and RPM of both shafts are known. For instance the torque of shaft (2) is: 35 × 63000 –––––––––– = 5520 inch-pounds. The torque of shaft (1) is therefore 63000 × 35 =1840 in. The torque of the driving and driven shafts is inversely proportional to the RPM. lbs.

The overhung mounting produces an entirely dissimilar result. 4.. The load at the other bearing acts in the opposite direction to that of the applied load. The load on the opposite end bearing is generally relatively small.) Fig. The thrust may act from left to right or from right to left. This load passes from the shaft to the inner ring through the balls to the outer ring and thence to the housing. 2 Radial Loads A radial load is one applied at right angles to the axis of the shaft. overturning moments. and the other bearing to take thrust in the opposite direction. i. 3. In the majority of cases. (2) Overhung.) The straddle mounting is the most commonly used in supporting shafts. The load on the bearing nearest to the point of application acts in the same direction as that of the applied load. although generally the thrust in one direction may be only a ‘‘locating’’ or nominal thrust. (See following page. The resultant load is indicated by the diagonal line.) In the straddle mounting. A radial load is sustained by not more than onehalf of the balls in the bearing. or it may alternate. . The ideal mounting for a ball bearing is where one bearing takes thrust in both directions. however. the thrust acts in one direction only. the radial load is divided in inverse proportion to the distance from the point of application of the load to the center of the bearing. The ‘‘opposed’’ method of mounting allows one bearing to take thrust in one direction. the radial load passing from a revolving housing through the bearing to a stationary shaft. the radial load is due to two or more components such as tangential forces. In some cases this condition may be reversed. The effect of this is to produce on the nearest bearing a load greater than the original radial load. In this. etc.Load Computations Bearing Loads Radial and Thrust Loads MRC Bearing Services The reactions at the bearings act in a direction opposite to the direction of the load. such as weights of shaft and other revolving parts. More often. which also shows the direction in which the shaft would move if not restrained by the bearing. Radial loads are supported by a pair of bearings which are mounted in one of two different manners: (1) Straddle. Combined Radial and Thrust Loads One bearing of the pair sustains both radial and thrust loads. the load is applied at a point outside of the two bearings. A radial load may be due to a single force. 356 Thrust Loads A Thrust or End Thrust load is one that acts in the same direction as the axis of the shaft. Its effect is to push the entire circle of balls against the race shoulder. Horizontal mountings always require provision for thrust in both directions.

Plus.A Composite Housing with Integrated Performance Features MRC Bearing Services • A polyurethane-filled housing base enables the unit to meet flush with its mounting surface. • 300 Series stainless steel bolt hole inserts provide added strength to each housing foot and prevent corrosion. Light gray polyamide composite housing resists corrosion. enabling the unit to fully compensate for initial bearing seating misalignment. – pillow blocks – two. Insert bearing is prelubricated with USDA approved grease. Flush surface-tosurface mounting eliminates gaps — potential areas for contaminants to collect. It is constructed of a thermoplastic composite material that can be up to 61% lighter than cast iron housings. Advantages of the HDi Series: • Complete ZMaRC coating on all housing surfaces for long-term corrosion resistance. protected with MRC’s proven ZMaRC coating. • Two-part sealing for maximum protection Like all Marathon bearing units. eliminate the flaking problems associated with nickel-plated products. lubed-forlife. eliminating areas where moisture and product can collect. • All HDi units are factory lubed-for-life with USDA approved H1 grease. And since there is no need for relubrication. continuous grease purge is never a problem.or four-bolt flange – tapped base 387 . The HDi Series is available in the following housing designs: – pillow blocks – two.HDi ZMaRC® Coated Cast Iron Units with ZMaRC coated Insert Bearings The heavy duty cast iron housings.) The added strength and durability of the Marathon HDi housings make them particularly well suited for applications in red meat. • HDi units require no relubrication. even in a washdown environment—saving time and money—while providing a cleaner-running unit. The housings are matched with our ZMaRC-plated. As with all Marathon products. • Housings and bearings are resistant to the majority of common washdown solutions. resulting in a more sanitary housing design. (See page 5 for more details. pork and poultry processing facilities where both housing strength and corrosion resistance are a concern. • ZMaRC coating will not flake off. Marathon HDi units contain an AISI 304 stainless steel inner seal and outer seal. • Open spaces on bases and backs of ZMaRC-coated housings are filled with polyurethane. MRC’s patented two-part stainless steel seals allow the units to operate in heavy washdown environments without regreasing. These components work in tandem to form an extremely effective sealing system. The HDi series provides a number of cost-saving and performance benefits. quality insert bearings. Exposure to extremely aggressive washdown chemicals is another reason to choose these stainless units. these units are machined from solid stainless plate.and four-bolt flange – tapped base MRC XDs Extreme Duty Machined Stainless Steel Mounted Units These housings are AISI 300 series cast stainless steel with MRC’s proven stainless steel insert bearings. the safety factor inherent in the cast steel housing is desirable. these housings offer even better surface roughness since all surfaces are machined. The XDs cast stainless housings were designed from the ground up for use in food and beverage applications. MRC’s excellent stainless steel insert bearings are used. The cast stainless housings are the strongest housings offered in the Marathon family. Also. such as in cases where workers pass below a portion of a machine. Whether the application involves heavy loads. hydrogen peroxide and other chemicals. in applications where failure of the housing could result in injury. The XDs units’ smooth cast surfaces minimize the material trapped on the surface allowing a more thorough cleaning. In addition to the styles listed above. These are especially suited for applications where surface roughness is critical. there are extremely challenging applications that require a even more durable unit—the XDs line of Marathon units. Just like the cast stainless units. While composite and plated housings are resistant to most of the chemicals in use today. Consideration was given to surface roughness as well. the XDs units are up to the challenge. Like the other members of the Marathon family. However. For any application where loads are very heavy or where shock loads are possible. . aggressive chemicals or intolerance to bacteria buildup. such as instances where chronic bacterial problems have existed. rather than using a cast housing. MRC Bearing Services Marathon XDs is MRC’s top of the line unit. made of an AISI 300 series stainless material. As with the cast housings.and three-bolt flange – piloted flange units All machined housings are available through the MRC MTO (Made To Order) program. they can be susceptible to some strong concentrations of chlorine. there are no unnecessary recesses or cavities to trap debris. the extra strength and toughness of the stainless steel housings are a benefit. Due to this manufacturing difference. The bases are cast flat with no recesses to trap debris and bacteria. are not affected by those same chemicals. These units also utilize AISI 300 series stainless steel but.Extreme Duty Cast Stainless Steel Mounted Units Composite housing units are suitable for many food and beverage industry applications. the following housing styles are also available: – three-bolt bracket flange – wide and narrow slot take-up units – compact two. and the exposed surfaces of the housings have no unnecessary crevices or pockets. 388 MRC can also offer additional housing styles in machined stainless steel. the XDs series incorporates the proven insert bearing design and patented sealing arrangement and are also greased for life and maintenance free.
