Falk™ Steelflex® Grid CouplingsRedefining Total Coupling Value (English-Inch) Falk™ Steelflex® The Simplest, Most Cost-Effective Coupling The Falk name is synonymous with grid couplings, as well as using shot peening to increase fatique strength and torque ratings. Features That Give Steelflex the Lowest Lifetime Operating Cost Steelflex redefines total coupling value up to 7.5 million in-lb, 932 000 Nm torque. Steelflex offers simpler initial installation than gear couplings, and our new HD design outlasts competitive gear couplings 2 to 1. Longer Life Tapered grids, made of high strength alloy steel, are quenched and tempered to spring hardness. The grid surface is then precision shot peened to compress the surface molecules. The unique “replace in place” design eliminates the need to move hubs or re-align shafts, reducing element change-out time. When you look (see chart below) at the overall savings in initial costs, spare parts costs, and labor costs for installation, alignment and replacement - plus improved ratings and a 5 Year Heavy-Duty Warranty - it’s easy to see what Steelflex Grid Couplings have over the competition. No other coupling in the torque range can touch Steelflex for cost-effective performance and reliability. The effect is a dramatic increase in rating, providing reserve strength for longer life or allowing a smaller size coupling to be selected. This precision technology was originally used in the production of sophisticated aircraft components. Extended Maintenance Periods Now you can install Steelflex and lubricate it with Falk Long Term Grease (LTG) and forget periodic, routine maintenance for five years. Falk LTG grease was developed specifically for couplings. It resists the separation of the oil and thickening agent that occurs in typical greases. Coupling Lifetime Operating Costs 150 HP (112 KW) @ 68 RPM The initial use of Falk LTG coupling grease will eliminate routine lubrication cycles while still providing the necessary lubrication to the tapered grid.

Initial Costs Labor Costs to Install & Align Spare Parts Costs Replacement Labor Costs 2 I 8,000 With LTG, Steellflex combines the high torque performance of a gear coupling and the low maintenance of a disc or elastomer coupling. Type HD Couplings The Preferred Replacement for Gear Couplings  Durable Nitrile Seals are heat resistant to 275ο F. (135ο C.)  Powder-coated covers provide chemical resistance. Quick, Easy Installation… Replace-In-Place Design The grid is the wearing member of a Steelflex coupling and it is a fraction of the complete coupling cost. Tapered grids are accessible through the quickly removable cover. The replace-in-place design of the replacement grids allows them to be dropped in without the need to remove or reposition hubs or realign shafts as required with gear couplings and many elastomer designs When coupling-connected equipment must be moved, the job takes longer and costs a lot more. Equipment Protection Against Shaft Misalignment The grid is free to rock, pivot and float within the hub teeth. Generous misalignment capacity is provided without producing detrimental bearing side loads created by other couplings. Equipment Protection Against Shock/Vibratory Loads Steelflex HD Grid Couplings – The preferred replacement for gear couplings Torsional flexibility is the LIGHT LOAD LOW CONTACT ability of Falk PIVOTS Steelflex couplings to torsionally deflect when HEAVY LOAD subjected to normal shock or FLOATS vibratory loads, providing CONTACT INCREASES flexible accommodation to changing load conditions. Versatile Designs Consequently, Steelflex tunes the drive system. It absorbs impact energy by spreading it over an increment of time. It damps vibration and reduces peak or shock loads by as much as 30%. It is a true shock absorber for rotary motion, relying on the predictable resilience of the steel grid for torsional flexibility. ROCKS Two cover designs are available in the popular sizes. Standard spacer, piloted, high speed, brakewheel or disc, and controlled torque designs are also available. Worldwide Availability Steelflex couplings and component parts, are available in popular sizes and types. Our distribution centers and worldwide distribution network offer the largest stock of rough bore, finish straight bore and Taper-lock bushed hubs of any shaft coupling on the market. Plus, Steelflex grid couplings are warranted for 5 Years when lubricated with Falk LTG Long Term Grease. 3 Steelflex Selection Guide 4 35 Engineering Data Recommended Commercial Keys – Inch and Metric . . . . . . – Unless otherwise specified. . . . . . . .

This arrangement provides for high torques and a torsionally stiffer assembly with overload protection. It provides the shock dampening of a Steelflex grid coupling in a piloted design for floating shafts with a controlled torque feature for overload protection. LLC. It is a T41 controlled torque assembly mated to a standard flex half gear coupling. T42 COUPLING T50 COUPLING = T42/T50 ASSEMBLY PLUS G52 COUPLING = T42/G52 ASSEMBLY Either the T45 or T42 coupling can be used with a T50 or G52 coupling on the opposite end of the floating shaft to achieve different operational characteristics or preferences for grid or gear couplings.

The customer may incorporate a warning light or an alarm to the circuit to signal the operator of an overload or shutdown condition. the coupling or clutch slips at a predetermined speed. It is set at a required cutout speed and continually compares the actual speed of the driven shaft with the set cutout speed. Refer to Slip Torque Performance Charts on Pages 24 through 27 to determine if an automatic proximity sensor cutout switch is required.090-. Overhanging Hubs When the distance between shaft ends is greater than the Coupling gap or when the coupling or clutch hub length is greater than the usable shaft length. overhang one or both hubs. Dimension Y must be equal to or greater than dimension X for clearance fits. Page 42 or submit application details to Rexnord. The control box can be mounted in an approximate space of 3 inches wide by 3 inches deep by 5 inches high.00 CONTROL BOX SENSOR HEAD T41 HUB CABLE TO MOTOR JAM NUT SENSOR SUPPORT BRACKET An automatic proximity cutout switch in the motor starter control circuit of controlled torque coupling or clutch application is recommended for protection of connected equipment and coupling or clutch where damaging thermal buildup could develop. For Type T41. the drive is immediately ready for service (after overload is removed) without resetting the circuit at any point. The proximity cutout switch speed control is adjustable at the control box. it opens the motor circuit and the drag load stops the motor shaft. 2007. X Y X Y (421-110) 23 . When the underspeed cutout switch is wired for automatic reset. CAUTION: The effect of open keyways on coupling or clutch balance should always be considered. 1963. check key stresses or use a semi-standard long T hub listed in Table 23. if this results in less than one shaft diameter of hub engagement. or greater than Dimension X times .

The motor will not maintain normal operation if the overload has not been removed because the motor contractor circuit will reopen as soon as the start button is released. 2007. The coupling or clutch slip torque setting and operating speed determine the length of time a coupling or clutch can slip without exceeding its thermal capacity. 1 2 3 SIZE 40T41 & 44 5 4 2 1 1480 10 8 2 3 2 3 4 5 6 8100 2 3 4 5 6 81000 SPEED (RPM) 2 3 4 Automatic cutout switch required.
