Introduction

1. MZ Series Cam Clutch is Shielded by shield bearings on both ends, packed with a

special grease, and are ready for use. No additional lubricant is required.
2. For attaching pulleys, gears or sprockets to the clutches, insert hubs (with f7 tolerance

of ISOR773) along the inner surface of the outer race and screw the bolts (high tension) into

the tapped holes on the clutch end.
3. Recommended shaft tolerances are shown in the table on the lower left.
4. External thrust load should be supported by other devices, not by the Cam Clutch.
5. Use only a parallel key to secure the clutch to the shaft. Do not use a tapered Key.
6. When mounting the clutch onto the shaft, apply pressure to the inner race but never to the outer race.
7. Ambient temperature range is 5° to 40°C.

Overrunning clutch:for multiple-machine drives or to separate the inertia of masses of a

driven machine from the driving
machine after it has been switched off.
Indexing clutch:which turns a shaft step by step, thus achieving indexed material feed

or a variable speed.
Backstop clutch:to prevent a machine shaft turning backwards. In this case the

overrunning clutch acts as a brake.
