Magna Torque (MT)


Hilliard’s line of overrunning clutches is economically priced and ideally suited for backstopping and gearbox applications. Custom designs and rapid prototyping are available. The overrunning clutch can be used for ratchet-type indexing operations such as packaging equipment and printing presses. When used in conjunction with a torque arm to hold the output shaft, Hilliard overrunning clutches provide instant backstopping protection with zero backlash from reversed rotation whenever power to the conveyor’s drive unit is interrupted.

Applications

Industrial Fans - Material Handling - Packaging/Printing - Steel Industry

Type: Backstopping & Indexing

Sprag Clutches


Hilliard Sprag Clutches are designed for overrunning, backstopping and indexing applications. This clutch is a freewheeling device with an inner race and an outer race, either of which can be the input or output member. The input can drive the output in a chosen direction and permit the output to overrun in the same direction. The clutch consists of a cage full of steel sprags or wedges, located in the space between concentric inner and outer races. Power is transmitted from one race to the other by the wedging action of the sprags between them. Rotation in one direction causes the sprags to tilt and wedge, preventing rotation. This allows free rotation in the opposite direction.

Applications

Industrial Fans - Material Handling - Mining - Packaging/Printing - Printing Press

Type: Backstopping & Indexing
