Installation and Usage
1. MZEU (K)-C series Cam Clutch couplings make use of MZEU (K) series and CR type couplings without cover.
2. Mount the Cam Clutch loosely on the high speed shaft at first.
3. Accurately align both sprockets by checking with a straight edge on the teeth of both sprockets.
4. Check whether the clearance(S) between both sprokets are correct, then wrap the chainaround the sprockets.
5. Specify right hand (RH) or left hand (LH) as inner race overrunning direction from the view of Cam Clutch side
(*) See the above drawing.
6. The same lubricaion as for Tsubaki roller chain is necessary for the coupling chain.
7. Ensure that the chain is properly closed with a connecting link and that the closed of the spring clip is
installed in the same direction as the rotation of the outer race.
8. Model No.
MZEU K
No Mark : No keyway on the outer race.
K : Keyway on the outer race.
■ LUBRICATION AND MAINTENANCE
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.

Body (Basic type) is supplied with sealing adhesive.
1. Apply a suitable amount of oil before use.
2. As a general rule, the amount of lubricant should be level with the center of the shaft for overrunning or backstopping.
3. The E2 flange has three plugs. The E4 cover has a large plug for adding oil and two small plugs for checking and
draining.
4. Place the plugs, so that one is at the top and one is at the bottom. The center one should be level with the center of
the shaft.
5. Pour oil into the clutch until it overflows from check plug. After a few minutes, pour in more oil and check that it
overflows again.
