Bearing data

Boundary dimensions

Not standardized


For additional information → Tolerances

Inner ring: Geometrical tolerances tighter than P4 (table 1)

Outer ring: Geometrical tolerances tighter than SP (table 2)

Cross-sectional height (table 3):

  • graded into three height groups
  • very tight tolerances

The position of the maximum wall thickness of the rings is marked on one side of the inner and outer rings with an arrow. Two additional markings can be found on the outer ring side face (fig. 1):
