  M Series ball bearing clutches contain precision formed cams made from high quality steel that are hardened then precision finished. Our most versatile and custom configurable clutch, this unit is the workhorse of the industry. The unique finishing process provides a smooth cam surface resulting in uniform contact with the races, providing even load distribution and prolonged wear life. These clutch models are designed to mount on through shafts and are secured to the shaft by a matching key provided with each stock bore clutch. Grease lubrication for each series can be provided at no additional cost. Intended for high-speed outer race overrunning, incorporating a unique cam cage construction that uses centrifugal force to minimize cam drag. The driving speed of the clutch cannot exceed the rpm shown in the table for the inner race.
