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.
