When mounting sprockets or gears to the outer race, use the outer race outer dimension (dimension B) to make a centering flange in the gear or sprocket. Then attach firmly with bolts of tensile strength 10.9 or greater to the tapped holes in the outer race. 2. Please refer to MZ Series for usage and other types of installations.

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. 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. MZEU K No Mark : No keyway on the outer race. K : Keyway on the outer race. 24 Typical installation 1 E2
