Torque limiters and couplings are designed to slip during a torque overload, while still transmitting the adjusted torque. They provide dependable solutions to the problems of torque control and overload protection in power transmission equipment. These clutches include one or more friction discs mounted on an inner hub, a single nut adjustment to easily pre-sets the torque. Similar static and dynamic coefficients of friction provide for extremely smooth torque control.

Pneumatic Overload Release Clutch


The Hilliard Pneumatic Overload Release Clutch provides adjustable, on-the-fly 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.

Applications

Cable Winches - Material Handling - Oil & Gas - Packaging - Power Generation
