*Pilot bores are to be drilled into the part. Minimum values for d1 and d2 are given by the minimum bore diameter values in the MIKI PULLEY standard hole-drilling standards and maximum values from the maximum allowable drilled bore diameters.
*The nominal diameter for the bolt M is equal to the quantity minus the nominal diameter of the screw thread.

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

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