With more than 50,000 Rexnord Addax Composite Couplings installed around the world, Rexnord has more experience than any other composite cooling tower coupling manufacturer. These couplings are made with lightweight, advanced composite material to increase critical speed, reduce vibration and extend bearing life. As a result, they can reduce overhung bearing loads up to 80% compared to alternative metal couplings. Rexnord Addax Composite Couplings are designed to your specifications and made to order.
Rexnord understands the importance of protecting critical production systems from the effects of damaging shock loads. Falk True Torque Fluid Couplings provide consistently longer, smoother, time-controlled starts with a wide range of starting power torque. Ideal for conveyors using multiple drives, Falk True Torque Fluid Couplings can allow for staggered motor starting and load sharing as well.
