Notes：1.Dam=(Damax+Damin)/2
......Damax-Da maximum measured value of Da.
......Damin-Da minimum measured value of Da.
....2.Dimensional tolerances for spherical inside diameter of housing are classified into H7 clearance fit, K7 for interference fit and J7 for intermediate fit between H7 and K7.
....3. When H7 fit is applied, the self-contained bearings are equipped with locking-pins.
