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.
2. We recommend a Shaft tolerance of h7, and the DIN 6885.1 keyway is
standard.
3. The clutch is delivered with a Basic type Cam Clutch, E3 torque arm and
E4 cover as separate parts.
4. Clean the surface of both ends of the outer race and the contact surface
of E3 torque arm and E4 cover.
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 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 Model No’s. MZEU12 to MZEU80, before mounting the E4 cover to the
clutch attach the end plate with bolts. Refer to installation example 4.
10. For Model No’s. MZEU90 to MZEU150, before mounting the cover attach
the packing and end plate using sealing washers and bolts. Refer to
installation example 5.
11. Model No.
