The cam cage assembly is engineered for optimum performance and increased capacity. It is the most custom configurable and versatile clutch offered by Morse making it a workhorse in 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. They are secured to the shaft by a matching key provided with each stock bore clutch. They come standard as oil lubricated, but grease lubrication is available at no additional cost.
