  1. Tolerances for tapered bores.
  2. Diameter series 7 and 8 not covered by ISO 492:2014.
  3. Applies to groove ball bearings only, except for self-aligning ball bearings.
  4. Applies to inner rings and outer rings of bearings of matched bearing sets consisting of two or more bearings. Does not apply to universally matchable angular contact ball bearings.
  5. No values have been established for capped (sealed or shielded) bearings.
  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.
