CDU (Continuous Drive Unit) Series Overrunning Clutches are designed to be robust for the most difficult applications.

Generally used as an indexing clutch where a compact package is desired.

Drawworks clutches are designed for use with Hydromatic® brakes on drilling rigs.

The HPO series is especially designed for high speed outer race overrunning applications, such as high speed dual drives or standby drives.

Available in six sizes, the Formsprag RL Clutch is a sprag type no-back which permits transmission of driving torque from input to output shaft in both directions of rotation, but restrains any feedback torque of the driven load from rotating the output shaft in either direction.

Model SB (shaft bore) automatic pump backstopping clutches feature a high torque density and require no adjustments or controls.

SBI Series In-line Mounting Ball Bearing Supported clutches are comprised of an HPI clutch with an extended shaft (inner race) for in-line mounting. The extended shaft provides a convenient way to mount a coupling to accommodate the misalignment in the in-line application.
