Product Details

Transmits torque between the shaft and the housing in one direction, and allows free overrun in the opposite direction. The patented design utilizes the same low profile and radial section as drawn cup needle roller bearings. The units are compact, light in weight, and operate directly on a hardened shaft.

-FS" in the suffix for the RC and RCB call out stainless steel springs and are capable of higher operating temperatures and significantly higher engagements per minute
A polymer spring is standard for the RC and RCB
A stainless steel spring is standard for the FC, FCS, FCL, FCB and FCBL
A hardened and machined shaft or an "IR" Inner Ring is required for optimal performance
A press fit into the housing is required
