Centrifugal clutches
Centrifugal clutches – No-load start-up for your application
Do you need a no-load motor start?
Our centrifugal clutches have been making 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 are set in rotation, a radial force acts that pushes them outwards. Up to the defined cut-in speed, this force is compensated by springs. Once the cut-in speed is reached, the friction linings make contact, torque builds up, and the application is accelerated to nominal speed. Through spring design, friction material, size and number of elements, we tailor the cut-in speed and torque precisely to your application.
As the slip phase is converted entirely into heat, a short slip phase is crucial – our organic friction linings dissipate the resulting heat efficiently via the housing and the surrounding area.
An overview of our
Two proven types of construction
hub
- Fly-out elements guided via dovetail profile
- torque transmission independent of the direction of rotation
- Servo amplifier increases the transmissible torque
centrifugal clutch with located pivoting flyweights
- flyweights guided with low backlash via pin
- heavy-duty support plate for low-vibration and low-noise operation
- Self-amplification as with a duplex drum brake; in the opposite direction, approx. 50 % capacitance
No matter which version suits your application and which motor you use – we manufacture the coupling individually to your requirements, whether with a parallel key connection or a taper.
