*Max. rotation speed does not take into account dynamic balance.

*Static torsional stiffness values given are from measurements taken at 20℃ .

*Values for moment of inertia and mass are those when the cylindrical hubs 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 nominal diameter for the bolt M is equal to the quantity minus the nominal diameter of the screw thread.
