*The bore diameters marked with ● are supported as standard bore diameter.

*ø11 and below have no keyway; ø12 and above can be processed for old JIS standards, new JIS standards, and new standard motors.

*The only standard processing of bore diameters of the ALS-095 and ALS-105 are for new JIS standards and new standard motors.

*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.

*Bore diameters whose fields contain numbers are supported as the standard bore diameters.

*Bore diameters whose fields contain numbers are restricted in their rated transmission torque by the holding power of the shaft connection component. The numbers indicate the rated transmission torque value [N·m].

*The recommended processing tolerance for paired mounting shafts is the h7 class. However, for a shaft diameter of ø35, the tolerance is -0.025 to +0.010.

*Bore diameters between the minimum and maximums shown in the dimensions table are compatible, but bore diameters other than those shown in the above table require other arrangements. Contact Miki Pulley for details.
