ML Series Handling Precautions
- 1. H6 or H7 is recommended for the bore finish tolerance of sprockets, gears, pulleys, and other items to be mounted.
- 2. Finish tolerance of h6 or h7 is recommended for the shaft on which the ML series is mounted.
- 3. Use JIS B1301-1996 (new JIS) parallel keys (standard type) for keys to be installed between the outer race of the ML series and the sprocket, gear, pulley, etc. to be mounted, and between the shaft on which the ML series is attached and the inner race of the ML series. Note that the key dimensions of the outer race are not in accordance with the relationship between the shaft diameter and key as specified by JIS. Keep a clearance between the top of key and keyway.
- 4. When installing pulleys, etc., if the radial load acting on the ML series during overrunning exceeds the allowable radial load for overrunning of the ML series, install a separate bearing to support the load on the load-bearing part as shown below.
- 5. Use of ML-2GD series is recommended when there is a lot of dust around, when oil unsuitable for cam clutches is splashed, or when grease leakage is to be prevented. The ML-2GD series is equipped with a dust seal to prevent intrusion of foreign matter. The maximum overrunning rotation speed of the ML-2GD series is only about 80% of that of the ML series.
- 6. When mounting the ML series on a shaft, check the direction of rotation and apply force only to the end face of the inner race to mount it gently.
- 7. External thrust load should be supported by other devices, not by the Cam Clutch. Do not use helical gears or other gears that are subject to thrust load during use, as this may cause malfunctions.
- 8. Ambient temperature for use is -30°C to 40°C.
- 9. For more information on lubrication and maintenance, click here.
Mounting Examples
・When not using bearings

Check the rotation direction of the Cam Clutch and install a retaining ring in the retaining ring groove on one side.
Install sprockets and other transmission parts using parallel keys.
Install the retaining ring in the other retaining ring groove.

ML Series ML-2GD type [With dust seal ]
Mounting Examples
・When using bearings

Install bearings, V-pulley and other components on the shaft, and attach spacers.
Check the rotation direction of the Cam Clutch and install the housing to be attached to the pulley, etc., using a parallel key to the outer race.
Attach the included retaining ring (for shaft) to the outer race.
After installing the ML series to the shaft, securely fasten the V-pulley and other parts with bolts strength classification 10.9 and spring washers .

Mounting Examples
・Mounting method to the shaft

After checking the rotation direction of the Cam Clutch and installing it, secure it to the shaft with a retaining ring or end plate and bolts.
Install gently by applying force only to the end face of the inner race.
