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. Model No’s. MZEU12 to MZEU80 sprockets and other torque transmitting factors can be
used with the standard flange. Refer to installation example 1.
3. We recommend a Shaft tolerance of h7, and ISO R773 (DIN 6885.1) keyway is standard.
4. We recommend a tolerance of E H7 for the sprocket and other parts.
5. Clean the surface of both ends of the outer race and the contact surfaces of the flange,
sprocket and the other parts.
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.
8. When installing standard flanges, sprockets and other equipment to the clutch fit them
around the bearings and screw the bolts into both ends of the outer race.
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.
