Static torsional spring constant, inertia moment, and mass values are for cases of maximum shaft diameter.
The lateral, angular, and axial misalignment values shown are for each occurring individually. When multiple misalignments are occurring simultaneously, the allowable maximum value of each will be reduced to 1/2.
