1. Concentricity of the inner race and the outer race are maintained by the plain bearing located between the outer race and the shaft. Radial load which works on the outer race is also supported by this plain bearing. The shaft must therefore be extended through the clutch outer race end.
2. Shaft tolerances
Recommended shaft tolerances are as follows:
PB3~PB8
PB10~PB14
+0 -0.013
+0 -0.016
3. H6 or H7 is recommended for the dimensional tolerance of the bores for sprockets, etc. to be mounted on the sleeve.
4. The inner and outer races cannot be directly attached to the left and right shafts, respectively, and used as couplings. In this case, be sure to use with a flexible coupling (e.g., roller chain coupling).
5. There are two different directions of engagement of the inner race: right-hand engagement (RH) and left-hand engagement (LH). When ordering, be sure to indicate the direction of engagement of the inner race as viewed from the direction of the arrow. Be sure to check the engagement direction before installation and operation.
6. Please use type-2 of JIS B1301-1959 (old JIS) parallel keys. Note that the keyway dimensions of the outer race are not in accordance with the relationship between the shaft diameter and keyway dimensions specified by JIS.
7. When used at high-mid speeds, care must be taken to avoid heat generation due to overrunning. Sufficient life cannot be expected if the temperature of the cam clutch outer race is above 70°C. A different series should be selected or the operation conditions should be changed.
8. For indexing, oil lubrication is recommended.
9. Do not apply thrust load to the cam clutch. External thrust load should be supported by other devices, not by the Cam Clutch.

11. Be careful not to overtighten the hexagon socket set screws on the sprockets, etc. that are attached to the outer race.
