The Hilliard Corporation’s linkless centrifugal clutches combine a dowel pin, vibration dampening bushing and a symmetrical spring design. The results are a long service life at an economical price. Other benefits include soft starts, load-free starting and overload protection. Hilliard’s centrifugal clutches are ideal for applications such as fans, blowers, conveyor drives and mills. Our engineering and manufacturing capabilities offer a wide range of choices, from common mounts to custom designs.

The patented Hilliard Extreme Duty Centrifugal Clutch has been engineered in pulley and sprocket versions to provide long service life and is ideal for retrofit or new equipment applications. A thermodynamically designed clutch shoe increases the clutch’s capacity to absorb heat without damaging the integrity of the clutch.

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.

The Hilliard PTO Clutch can be used for most start and stop applications that require positive engagement/disengagement and overload protection. With full control of clutch engagement, the PTO Clutch has adjustable torque setting and a bearing engagement collar.
