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. The clutch is delivered with a Basic type Cam Clutch, E2 flange
and E3 torque arm as separate parts.
4. Clean the surface of the outer race at both ends and the contact
surfaces of the E2 flange and the E3 torque arm.
5. For Model No’s. MZEU90 to MZEU150, apply seal adhesive to the
surface of the outer race at both ends.
6. Check the direction of rotation and attach the E2 flange and the E3
torque arm to the clutch.
7. By installing both the flange and sprocket on the opposite side, the
direction of rotation can be changed.
8. When mounting the clutch onto the shaft, apply pressure to inner
race but never to the outer race.
9. For high speed Indexing applications (More than 50 c/m) a strong
spring type is recommended.
10. Model No.
MZEU K
No Mark : No keyway on the outer race.
K : Keyway on the outer race.
