[ ! ] Tolerances are not controlled for the shaft bore diameters of d₁ and d₂.
[ ! ] Recommended Fit Tolerance of Applicable Shaft Diameter: h6 and h7.
[ NG ] CPDT cannot tolerate lateral misalignment.
[ ! ] 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.
