*Max. rotation speed does not take into account dynamic balance.
*Dynamic torsion spring characteristics are non-linear, so use a dynamic torsional stiffness that is at least roughly 20% of rated torque.
*The dynamic torsional stiffness is about 1.3 times that of the static torsional stiffness.
*Values for moment of inertia and mass are those when the cylindrical hub and flange hub have pilot bores.

*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 TK dimension is the bolt mounting pitch diameter of the fl ange hub or paired mounting part.

*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.
*We can also machine splines. Please contact Miki Pulley.
