* The shaft tolerance for standard bore diameter is h7 (h6 or g6): designation B. However, for a shaft diameter of ø35, the tolerance is ＋ 0.010~－ 0.025 .
* Shaft tolerances j6/k6: designations J/K are optional, and are only supported for bore diameters marked with ○ .
* Bore diameters marked with ● or numbers are supported as the standard bore diameters. Consult Miki Pulley regarding special arrangements which may be possible for other bore diameters.
* Bore diameters whose fields contain numbers are restricted in their rated torque by the holding power of the shaft connection component because the bore diameter is small. The numbers indicate the rated torque [N•m].

* The shaft tolerance for standard bore diameter is h7 (h6 or g6): designation B. However, for a shaft diameter of ø35, the tolerance is ＋ 0.010~－0.025 .
* Shaft tolerances j6/k6: designations J/K are optional, and are only supported for bore diameters marked with ○ .
* Bore diameters marked with ● or numbers are supported as the standard bore diameters. Consult Miki Pulley regarding special arrangements which may be possible for other bore diameters.
* Bore diameters whose fields contain numbers are restricted in their rated torque by the holding power of the shaft connection component because the bore diameter is small. The numbers indicate the rated torque [N•m].
