* 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.

*If you require a product with an LS dimension other than that above, contact Miki Pulley with your required dimension [mm]. Please contact Miki Pulley for assistance if LS ≧ 1000.
*The nominal diameters of each bolt and tap are equal to the quantity minus the nominal diameter of the screw threads times the nominal length. The quantities for the pressure bolt M1 and detachment screw hole M2 are quantities for the hub on one side.

*The bore diameters marked with ● or numbers are supported as standard bore diameter.
*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 value [N·m].

* 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.
