DC Sprag Freewheel Clutch,Stieber Clutch

DC-Freewheels are sprag-type clutch elements with a double cage and individually energised sprags.The sprags are guided and retained by the inner cage, outer cage and the ribbon spring.They are completed with inner and outer races. The sprag cage assembly moves with the outer race. The driving speed is restricted, as the sprags centrifugally disengage at high speed. STIEBER can supply outer races secured by bolts, a keyway or a press fit. The inner races can have double, single or no bearing seats if separate bearing support is provided by the customer. DC units may be used as backstops, overrunning clutches or indexing freewheels with either the inner or outer races overrunning.
