M Series clutches incorporate a dual ball bearing supported design that includes high-quality hardened, precision formed and finished steel cams in a cage. The cam cage assembly is engineered for optimum performance and increased capacity. This clutch design provides for the most custom configurable and versatile clutch offered in the industry.

The dual bearing design maintains race concentricity to help provide the most uniform loading of the cams. The M series clutch is designed to mount on through shafts that are secured to the shaft by a matching key provided with each stock bore clutch. Oil lubrication is standard, and grease lubrication is available at no additional cost. This general purpose clutch is intended for backstopping, indexing and overrunning (inner and outer race) applications.

There are four different versions: MG, MI, MR and MO, each customized to specific applications. A full line of accessories are also available to accommodate many different applications:

  • couplings
  • torque arms
  • stub-shaft adapters
  • oil reservoirs
