Integrated Freewheels FXRV Bearing

Integrated Freewheels FXRV are sprag freewheels without bearing support and with sprag lift-off X. They consist of the Integrated Freewheels FXM with additional torque limiter.
The sprag lift-off X ensures a wear-free free­wheeling operation when the inner ring ­rotates at high speed.
Advantages
Protection of gearboxes from overload by unequal load distribution in multiple drives
Protection of gearboxes from dynamic peak torques during the locking process
Smaller gearboxes can be used without negatively effecting the safety
Protection of the backstops, as dynamic peak torques are reduced by temporarily slipping.
