The 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 provide at no additional cost.
MG300A – 700A Series Primarily used for general duty applications, Overrunning, back-stopping and light duty indexing. The MG model offers precise spring energizing to provide long overrunning wear life.
MI300A – 700A Series Recommended for high performance indexing, used on applications greater than 150 strokes per minute or applications requiring high indexing accuracy. Incorporating a patented, low inertia
cage and heavy duty energizing spring for quick cam reaction.
MO300A – 700A Series Made with felt grease seals to minimize seal drag for high speed inner race overrunning applications. The MO model is delivered with standard grease lubrication.
MR300A – 700A Series
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.
