*All standards starting from ø11 are the same as those in the old JIS standards column.

*For ALS-014, set screw size is M3.

*Positions of set screws and keyways are not on the same plane.

*Set screws are included with the product.

*Positioning precision for keyway milling is determined by sight.

*Contact Miki Pulley when the keyway requires a positioning precision for a particular flange hub.

*Consult the technical documentation at the end of this volume for standard dimensions for bore drilling other than those given here.

*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 bore diameter of ø35, the shaft 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.
