Backstopping clutch The Hilliard Corporation

Hilliard MT Overrunning Clutches combine high torque, high speed capabilities, easy field repair and low cost – all in a compact size. With most overrunning clutches, shaft size is a major consideration. Hilliard’s new roller ramp design allows for greater shaft sizes than comparable size clutches offered by other clutch manufacturers. The assembly features the cam surface precision machined within the housing instead of the inner member, giving it the ability to reach much higher overrunning speeds and to attain greater torque in a much smaller space.

Typical applications include general backstopping and overrunning, such as suspended conveyors, indexing or ratcheting, and gear boxes.

Features:
• Flexible packaging as a clutch or clutch coupling
• Increased torque
• Compact design
• Increased shaft sizes in same physical-size units
• Custom mechanisms available
• Failure in overrunning mode; does not lock up

Clutches are available in various models from 82 to 43,600 lb.ft. at 1,000,000 cycles. Custom designs and rapid prototyping are available.
