*The rated torque of the coupling may be limited for bore diameters marked with *1. Consult "Standard Bore Diameters".

*The øDB value is measured assuming that the head of the clamping bolt is larger than the external diameter of the hub.

*The nominal diameter for the clamping bolt M is equal to the quantity minus the nominal diameter of the screw threads, where the quantity is for a hub on one side.

*For items marked with *2, d1 or d2 may be from ø3 to ø7 in some cases. If d1 or d2 is ø8, this value is 6.

*For items marked with *3, d1 or d2 may be from ø3 to ø7 in some cases. If d1 or d2 is ø8, then this is M2. The M2 tightening torque is 04 to 0.5 N·m.

*The recommended processing tolerance for paired mounting shafts is g6・h6・h7 class. However, for a shaft diameter of ø35, the tolerance is -0.025 to +0.010. Consult Miki Pulley for special tolerances other than h7(h6・g6) class.

*Bore diameters marked with ● , ○ , or numbers are supported as the standard bore diameters.

*Bore diameters marked with ○ have restrictions on the inner diameter of the element, so they can only be used with d2 side hubs. Example of product that cannot be manufactured: SFC-020SA2-11B-11B; example of product that can be manufactured: SFC-020SA2-10B-11B

*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].

*These range of applicable bore diameters is between the minimum and maximum bore diameters of the dimensions table. Consult Miki Pulley regarding special arrangements for other bore diameters.
