The MAXITORQ® Overload Release clutch is comprised of or standard mechanical multiple disc clutch with overload release features. The overload release occurs as a result of cams placed on the shifter sleeve and drive cup. When an overload occurs the discs slip, causing the cams to come into contact. The shifter or sleeve is then forced into a neutral position.

The MAXITORQ® Overload Release clutch is designed to protect a machine and its products against damage resulting from accidental overloading of the mechanism. The overload clutch comes with a ring type drive cup and hub adapters as a package, designed for a particular application. The driving ring cup connects the overload release clutch with either the driven or driving device.

We are able to modify our standard product, offer custom products previously designed by our own engineering staff, or custom design and develop a new product to meet your specific needs.

Special overload release shifters are available for clutch sizes 20 – 26. Shoes and studs are available for all sizes including 27 and 28 for riveting into shifter yokes designed by the customer.
A limit switch can be incorporated into the power input line. The clutches may be used on a continuous shaft, or as a cut-off coupling type for connecting two shafts.
