HOW IT WORKS

The Hilliard Extreme Duty Clutch Transfers Torque Through Speed-Dependent Engagement Force

Centrifugal clutches use rotational speed as the engagement trigger between input power and driven load. At low speeds, the clutch remains disengaged, allowing the engine to start and idle without load. As speed increases, centrifugal force acts on internal components, causing them to move outward and engage the clutch drum. Hilliard Extreme Duty Clutches are engineered to maintain consistent engagement behavior under varying load conditions, with design variations optimized for specific duty requirements and equipment classes.

Why the Right Heavy-Duty Clutch Matters

Speed-Triggered Engagement

Clutch engages only when rotational force overcomes internal spring resistance.

Variable Torque Transmission

Torque transfer increases as engagement force builds with speed.

Controlled Slip Phase

Temporary slip occurs during engagement to manage load acceptance.

Thermal Load Response

System is designed to tolerate heat generated during repeated engagement cycles.
