MG MI SERIES Cam Clutch Bearing
MODELS MG300 TO MG1300/MI300 TO MI1300
For General Applications
The MG/MI Series Cam Clutches feature a precision-engineered cam mechanism for zero-backlash, unidirectional locking.
Key advantages of cam clutch bearing:
High Torque Density: Compact design delivers maximum torque in minimal space;
Instant Engagement: Optimized cam profile enables ms-level response with no slip;
Extended Durability: Alloy steel + case hardening resists wear/shock, increasing service life by 50%+;
Quiet Operation: Low-vibration design, noise ≤20dB(A) for sensitive environments;
Lightweight (MI Series): 30% weight reduction for low-torque applications with lower starting torque.

Installation and Usage of Cam Clutch Bearing
1. MG Series Cam Clutch from Suma bearing vendor is used for inner race overrunning applications. MI Series Cam Clutch from Suma bearing vendor is used for indexing applications.
2. For attaching a pulley, a gear, or sprocket to the cam clutch bearing, insert the Cam Clutch into the hub of the device,
and screw the bolts (high tension) into the tapped holes on the clutch end. The tolerance bore of the hub
should be H6 or H7 of JIS standard.
3. Recommended shaft tolerances are as follows:
