Precision Load Limiter


Setco’s TensionSet 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 the tensioning load.


TensionSet is load sensitive and is resistant to changes in threaded rod conditions that would otherwise alter the relationship between tightening torque and pull force. It helps increase belt life leading to less down-time for machine maintenance and is retrofittable to many spindle brands.
