This type of Freewheel Clutch is designed without ball bearings to be assembled with customer connecting parts.
NHB are located on the 1st or 2nd stage gearbox and prevent reverse rotation of conveyor belts, pumps, elevators, etc.
NHB models are without bearing supported and with Centrifugal lift-off Sprag (CLS). The Centrifugal Lift-off Sprag (CLS) ensures a wear-free freewheeling operation when the inner ring rotates at high speed.
These types of clutches are used, where the speed of the shaft is higher. NHB models are used as Backstop/Holdback.
