Tolerance symbols and definitions → table
- 1) These deviations apply for bearings in the 8 and 9 diameter series only.
- 2) These deviations apply for bearings in the 0 and 2 diameter series only.
- 3) Applies to inner rings and outer rings of bearings of matched bearing sets consisting of two or more bearings and universally matchable angular contact ball bearings.
- 4) No values have been established for capped bearings.
- 5) Applies to bearings prior to mounting and after removal of internal or external snap ring.
-
6)
Tolerance values have become half the values in accordance with the revised ISO standard (2014) because
SD is defined as perpendicularity of outer ring outside surface axis with respect to datum established from the outer ring face.
