Most bottle capping clutches today are magnetic, but of the synchronous design. The synchronous design uses two sets
of opposing magnets to achieve the desired torque. The result
is a noisy, ratcheting effect. These clutches tighten the cap much like an impact wrench
tightens the lugs on an automobile tire. With today´s thinner materials, higher speeds and the need for more precise torque, synchronous clutches are quickly becoming obsolete in the workplace.
We use the highest quality magnets, design techniques, and hysteresis materials in order to bring you the best clutch for
your money. We custom build OEM designs, and offer standard stainless steel bottle capping clutches to replace most
With the hysteresis type capping clutch, input and output torques are transmitted through air with the help of high quality permanent magnets and precision ground hysteresis material (AlNiCo). The benefit is a completely smooth and repeatable torque transmission to your capping application. The result is accuracy and longevity packaged into a capping clutch.
Torque adjustment is obtained by gradually varying the overlapping surfaces of the hysteresis and magnetic materials. The widest possible torque adjustment is achieved with this design.
