Notes
(1) 0.6 mm is included in this dimension classification.
(2) The deviation and variation of the outer ring width are determined based on the inner ring values of the same bearing. The variation of the outer ring width of P5 and P4 is obtained from the table "Tolerance of outer ring of radial ball bearings" below.
Remarks
- The upper tolerance of the bearing bore diameter defined in this table is not applicable to the distance within 1.2 times the chamfer dimension rsmax from the ring face.
- ABEC1, ABEC3, ABEC5 and ABEC7 of the inch series is equivalent to P0, P6, P5 and P4 of the metric series, respectively.
- Please contact our company when the tolerance class is P2 or the tolerance is not indicated in the above table.

Notes
(1) 2.5 mm is included in this dimension classification.
(2) This is applicable when the snap ring is not mounted.
(3) The width variation of the outer ring of P0 and P6 is based on the tolerance of the inner ring.
Remarks
- The lower tolerance of the bearing outside diameter defined in this table is not applicable to the distance within 1.2 times the chamfer dimension rsmax from the the ring face.
- ABEC1, ABEC3, ABEC5 and ABEC7 of the inch series is equivalent to P0, P6, P5 and P4 of the metric series, respectively.
- Please contact our company when the tolerance class is P2 or the tolerance is not indicated in the above table.
