Product Description

Features
Complete Freewheels FRX and FRZ are sealed sprag freewheels with ball bearings and sprag
lift-off X or sprag lift-off Z. The freewheels FRX and FRZ are used as:
Backstops
Overrunning Clutches

Application example
Complete Freewheel FRX 600 as an overrunning clutch in the drive unit of a conveyor belt
system with additional creep drive. The free - wheel with shaft coupling is installed between the main motor and the creep drive. When the creep drive operates, the freewheel is in driving operation and drives the belt at low speed. During normal operation (freewheeling operation), the main motor drives and the inner ring overruns and the creep drive is automatically disengaged. With this high speed, sprag lift-off X is used; the sprags work in freewheeling operation without contact and are wear-free.
