The initial use of falk LTG couplinggrease will eliminate routine lubrication cycles while still providing the necessary lubricationto the tapered LTG, Steellflex combines thehigh torque performance of a gearcoupling and the low maintenanceof a disc or elastomer Steelflex The simplest, most cost-effective couplingThe falk name is synonymous with grid Couplings , as well as usingshot peening to increase fatique strength and torque redefines Total Coupling Value up to million in-lb, 932 000 Nm torque.

3 Steelflex offers simpler initial installation thangear Couplings , and our new HD design outlasts competitive gear Couplings 2 to 1. The unique replace in place design eliminates the need to movehubs or re-align shafts, reducing element change-out you look (see chart below) at the overall savings in initial costs,spare parts costs, and labor costs for installation, alignment andreplacement - plus improved ratings and a 5 Year Heavy-DutyWarranty - it s easy to see what Steelflex grid Couplings have over thecompetition.

Refer to the Factory for details. If Rexnord is to supply Coupling hubs bored for Taper-Lockbushings, the bushing manufacturer MUST be noted on theorder. Consult the Factory when limited end float is Notes Peak torque capacity is two times the published rating. Torqueratings for hubs with bushings differ from those shown, refer toTable 19, Page 39. Consult the Factory for higher speeds. Maximum bores are reduced for hubs furnished with anINTERFERENCE FIT and a setscrew OVER the keyway.
