Overrunning clutch The Hilliard Corporation

Magna Torque (MT) for Backstopping and Indexing
Hilliard’s line of overrunning clutches is economically priced and ideally suited for backstopping and gearbox applications. Custom designs and rapid prototyping are available.

Roller Ramp (MTR) for Clutch Couplings, Dual-Drive & Turning Gear
There is almost no wear during freewheeling operations in the Hilliard roller-ramp designed clutch because rollers are free to rotate between the outer member and the inner cam. Typical applications for this clutch are blowers, pumps, fans, conveyors and forming rolls.

Enclosed Overrunning Clutches
Hilliard’s enclosed overrunning clutch incorporates superior MTR design in a totally enclosed package. Designed for power transmission operations, this clutch is totally contained in a stationary housing for constant protection from hostile environments or washouts.

High-Speed Overrunning Clutches
The Hilliard high-speed overrunning clutch provides positive engagement and high torque on demand. Featuring a unique roller-ramp design, the clutch when engaged transmits power via the precision-machined cam and roller assembly connected to the input shaft. Typical applications include hydraulic, electric, and pneumatic turbine starters; turbine drives, and turbine auxiliary drives.
