Formsprag Clutch FHB Series

Backstopping Clutch

Drop in replacement for competitor's design but with higher performance ratings.

The FHB backstop is mounted on a through-shaft with its inner race driven by a key, and its integral outer race torque arm prevented from rotating through a clearance fit interface with a fixed reaction pin. The reaction pin may also be used to provide axial restraint of the backstop on the rotating shaft.
