Installation and Usage
1. Model No’s. MZEU12 to MZEU80 are pre-greased and require no lubrication. The
operational temperature range is –40°C to +40°C.
Model No’s. MZEU90 to MZEU150 require oil lubrication. (Refer to lubrication and
maintenance on page 31).
2. We recommend a Shaft tolerance of h7, and ISO R773 (DIN 6885.1) keyway is standard.
3. We recommend tolerances of B H7 or H8 for sprockets, gears and other fitted parts.
4. The clutch is delivered with a Basic type Cam Clutch, E1 flange and E2 flange as
separate parts.
5. Clean the surface of both ends of the outer race and the contact surfaces of the flanges.
6. For Model No’s. MZEU90 to MZEU150, apply seal adhesive to the surface of the outer
race at both ends.
7. Check the direction of rotation and attach the E1 and E2 flanges to clutch.
8. When installing sprockets, gears and other equipment to the clutch, fit them on the
surface of the outer race and screw the bolts into the E1 flange.
9. By installing both the flange and sprocket on the opposite side, the direction of rotation
can be changed.
10. When mounting the clutch onto the shaft, apply pressure to inner race but never to the
outer race.
11. For high speed Indexing applications (More than 50 c/m) a strong spring type is
recommended.
12. Model No.
