*The shaft coupling employs friction, so rated torque is determined by bore diameter. The rated torque of the side with the smallest diameter serves as the rated torque of the coupling.
*Max. rotation speed does not take into account dynamic balance.
*The torsional stiffness, moment of inertia, and mass are measured for the maximum bore diameter.
