Bearing tolerance chart, table

Bearing tolerances and permissible values for the boundary dimensions and running accuracy of bearings are specified. These tolerances are regulated by standards such as ISO.

Actual tolerance values are listed in the following tables. The tolerance symbols used in the bearing tolerance standards tables refer to bearing tolerance table.

Tolerances for cylindrical bores
Diameter series 7 and 8 not covered by ISO 492.
Applies to groove ball bearings only, except for self-aligning ball bearings.
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.
No values have been established for capped (sealed or shielded) bearings.
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.

For double direction bearings, the values apply only for d2 ≤ 190 mm and D ≤ 360 mm.
Applies only to thrust ball bearings and thrust cylindrical roller bearings, each with 90° contact angle.
Not applicable for central shaft washers.
Not included in ISO 199.
ISO 199 uses symbol T.
