Hilliard Ball Detent Overload Release Clutches

Industrial Clutch Parts Ltd. distribute Hilliard overload release clutches in both pneumatic and mechanical operations. Suitable for a variety of applications, such as cable winches, material handling, oil & gas, packaging, power generation and food processing equipment. 

Hilliard pneumatic overload release clutch provides flexible overload protection by using air pressure to regulate torque. Air pressure puts force on the balls placed inside the pockets in the clutch and provides the means for torque transmission. By adjusting the air pressure, the overload torque can be increased or decreased accordingly.

Hilliard overload release clutches are manufactured and designed to provide accurate overload protection and automatically reset after the overload is cleared. The ball pocket design ensures the torque setting remains consistent over time. A manual version is available upon request, featuring bi-directional operation, single-position indexing, precise disconnects and washdown duty systems for food service.
