Today, these control system bearings are specified at vital control points on all classes of fixed and rotary wing aircraft, both commercial and military. With each new generation of aircraft, Shafer is there with advancing design concepts to meet the industry's needs. The following paragraphs describe a number of the beneficial features of Shafer roller bearings that contribute to their popularity among engineers in the aerospace industry. SELF-ALIGNMENT CAPABILITY The inner ring can be freely misaligned within rated limits. Long term stainless steel shields, to provide corrosion protection by keeping the reliability, especially under dynamic misalignment conditions, is lubrication in the bearing and contaminants outside. enhanced because the relative motion occurs on the rolling surfaces inside the bearing. RELUBRICATION IN SERVICE RADIAL AND THRUST CAPACITY Both annular and rod end bearings can be relubricated through the outer ring without disassembly or removal of the bearing from the Single row bearings are designed primarily for radial load airframe structure. Relubrication of a rolling element bearing can applications. They can, however, carry momentary or intermittent definitely help to extend service life far beyond that of a bearing that light thrust loads, but they are not designed for continuous thrust load is factory sealed and has no relubrication provisions. applications. Refer to Figure 1. The relubrication provisions for Shafer single row and double row bearings are such that lubricant is directed to the rolling contact In double row bearings, two rows of rollers are positioned around the surface area. See Figures 3-6. The spaces between the rollers are radial centerline of the inner ring. It is possible for the double row filled with grease. The grease from these reservoirs replenishes the bearing to carry pure radial or a combination of radial and thrust lubricant film on contact surface areas. loads. Pure dynamic thrust is acceptable if the contact angle is at least 15°. The load carried by the rollers is evenly distributed on the race surface, for maximum capacity even under severe misalignment. The rollers align themselves naturally, eliminating roller end wear and race surface scuffing. End-thrust loading is taken on the full roller contact area, not on the inner ring shoulders or retaining ring surfaces. Refer to Figure 2. Most rod end bearings shown in this catalog are equipped with the NAS516-1A fitting. When section size is too restricted, smaller nylon fittings are used. The Alemite 314150 nozzle can be used to relubricate through both ot these fittings. This nozzle will fit all standard grease guns and lubricating systems.

Ordinarily failure is due to fretting. depending upon the application. explaining the relationship between load and motion in a given Figure 12 application. When radial and axial loads occur simultaneously. in which event bearing life is less predictable. Since the internal design of the bearing and the angle of oscillation determine the number of contact stresses. Also. This value is then used in making the bearing selection. they must be combined to produce an equivalent radial load. Fretting is primarily wear. the evaluation of the effect of the oscillation angle can be divided into two categories. Failure is usually due to contact fatigue. At these lower angles of oscillation. MOTIONS Bearing life. redistribution of grease. This information is necessary in order to accurately determine the effects of load and motion on bearing life.FACTORS AFFECTING BEARING PERFORMANCE LOAD Aerospace bearings rarely experience a constant unidirectional load. in which case the life of the bearing is predictable. it becomes necessary to evaluate the effects of the degree of oscillatory motion upon the rated bearing life. from the rated oscillation of 90° included angle. adjacent roller paths do not One cycle involves a reversing load and 2φ° angular travel within an overlap. OSCILLATION ANGLE (DUTY CYCLE) In many areas of the catalog the term "cycle" is used to express either a rated or required bearing life. A required cycle or duty cycle can experience variances in load and movement. Angles of oscillation below 25° included angle. Therefore there is less opportunity for adequate included arc of φ°. Generally speaking. Angles of oscillation above 25° included angle. To properly select the bearing. circulation of grease in the bearing can be greatly assisted if the oscillation angles under 25° are interspersed with angles of motion above 25°. The direction and magnitude of the load may vary in an infinite number of combinations. The selection procedure on Page A10 will enable the designer to evaluate his application for the proper bearing selection. separated by the fretting threshold angle: 1. the designer must clearly define the duty cycle and the relationship between the bearing movement (angle of oscillation) and the applied load.the assumed mode of failure – is a function of the number and magnitude of contact stresses at any given point on the race surface. 2.
