TensionSet from Setco (Cincinnati, OH) is a load limiting device that ensures proper belt tensioning on motor drives, protecting shaft bearings and other components from premature failure. The patented and easy-to-install product rotates like a nut to generate pull-force on a threaded rod. The pull-force increases the distance between the pulleys on the motor drive and creates belt tension. When pull-force exceeds the load setting during tightening, TensionSet disengages internally to prevent over tensioning. Positive reverse drive causes the TensionSet to rotate in the reverse direction, removing tensioning load.
Four models are available with nominal load capacities ranging from 50 to 575 lbs. Various thread sizes and custom load settings are available upon request.
