Mounting and Coupling
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 isrecommended.
12. Model No. Description
MZEU K
No Mark : No keyway on the outer race.
K : Keyway on the outer race.
