1. Sprockets, gears, etc. to be mounted on the outer race should be inlet with the outer circumference B dimension of the outer race (see here) and securely attached with bolts of strength category 10.9 to the tapped holes on the outer race end face. The tolerance of its inlet section is recommended to be H6 or H7.
2. Shaft diameter tolerance of h6 or h7 is recommended.
3. Always use parallel keys (MG750 and above are delivered with a key) and keep a clearance between the top of key and keyway.
4. An air (internal pressure) vent hole is provided at the bottom of the inner race keyway, so please leave a gap (0.1 mm or more) between the ceiling of the key and the bottom of the keyway so that the air (internal pressure) can escape.
5. Please use type-2 of JIS B1301-1959 (old JIS) parallel keys.
(MG750 and above includes special keys which have a special height dimension.
The groove depth of the key against the shaft should be in accordance with JIS. )
However, the relationship between shaft diameter and key dimensions may not be as per JIS.
6. When inserting the shaft, apply pressure only to the face of the inner race only. Never hit the outer race.
7. If the clutch receives shock loads or is designed for use at full torque capacity, it is better to use a hardened key and shaft.
(Keys supplied with MG750 and above are hardened keys. )
Also check the shaft strength.
8. External thrust load should be supported by other devices, not by the Cam Clutch.
9. When used at high-mid speeds, care must be taken to avoid heat generation. Sufficient life cannot be expected if the temperature of the cam clutch outer race is above 70°C. Either another should be selected or oil bath lubrication or forced lubrication is required. For continuous overrunning, 1/3 or less of the maximum overrunning rotational speed is recommended.
10. Oil is not sealed in at the time of shipment. Supply an appropriate amount of oil before use.
11. When used at low speeds, oil may come out of the air holes for internal pressure adjustment. For use at 200 r/min or less, please request a quotation for specifications without air holes.
