CENTRIFUGAL CLUTCHES

Centrifugal Clutches — No-Load Start-Up for Your Application

Need a No-Motor Start?

Our centrifugal clutches have made it possible since 1982 — with a smaller, more cost-effective motor instead of expensive oversizing.

How Does a Centrifugal Clutch Work?

As soon as the centrifugal weights start rotating, a radial force pushes them outward. Up to the defined engagement speed, this force is offset by springs. Once the engagement speed is reached, the friction linings engage, torque builds up, and the application accelerates to its rated speed. By adjusting spring design, friction material, size, and the number of elements, we precisely tune the engagement speed and torque to your application.

Since the entire slip phase is converted into heat, keeping the slip time as short as possible is essential — our organic friction linings dissipate the resulting heat efficiently through the housing and surrounding air.

Two Proven Design Types

Profile Hub

Centrifugal elements guided via dovetail profile
Torque transmission independent of direction of rotation
Servo effect increases the transmittable torque

Privoting Shoe Design

Centrifugal elements guided via pin with minimal play
Solid carrier plate for low-vibration, low-noise operation
Self-energizing effect similar to a duplex drum brake, with approx. 50% capacity in the reverse direction

No matter which design fits your application or which motor you use — we manufacture the clutch to your exact specifications, whether with a keyway connection or a taper bore.
