*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 diameters for bolts M1/M2 are equal to the quantity minus the nominal diameter of the screw threads.
*The TK dimension is the bolt mounting pitch diameter of the flange hub or paired mounting part.

*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.

*Pilot bores are to be drilled into the part. Minimum values for 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 diameters for bolts M1/M2 are equal to the quantity minus the nominal diameter of the screw threads, where the quantity is for one side.
*The L dimension has a standard length of 1000 mm or less. Dimension L must at least allow enough space for an M1 bolt to be mounted.

*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.

*The nominal diameters for bolts M1, M2, and M3 are equal to the quantity minus the nominal diameter of the screw threads, where the quantity for clamping bolt M3 is for a hub on one side.
*The recommended processing tolerance for paired shafts is the h7 class.
