Installation and Usage
1. The clutch is delivered with a Basic type Cam Clutch, E2 flange,
E7 flange and each flange kit as separate parts.
2. Check the direction of rotation and attach the each flange to the
clutch.
3. When installing sprocket, gear and other equipment to the
clutch, fit them on the surface of the outer race or flange and
screw the bolt in to them.
4. By installing both option parts on the opposite side, the
direction of rotation can be changed.
5. When mounting the clutch onto the shaft, apply pressure to the
inner race but never to the outer race.
6. For high speed indexing applications (more than 50 c/min) a
strong spring type is recommended.
7. Refer to page 31 for other Usage.
8. Model No. MZEU K
No Mark : No keyway on the outer race.

using E7 flange to keep the centerline between the inner
and outer race.
