Notes (1) 0.6mm is included in the group. Remarks 1. The cylindrical bore diameter "no-go side" tolerance limit (high) specified in this table does not necessarily apply
(2) Applicable to bearings with cylindrical bores.
(3) Tolerance for width deviation and tolerance limits for the width variation of the outer ring should be the same bearing. within a distance of 1.2 times the chamfer dimension r (max.) from the ring face.

Tolerances for the width variation of the outer ring of Class 5, 4, and 2 are shown in Table 8.2.2. 2. ABMA Std 20-1996: ABEC1⋅RBEC1, ABEC3⋅RBEC3, ABEC5⋅RBEC5, ABEC7⋅RBEC7, and ABEC9⋅RBEC9
(4) Applicable to individual rings manufactured for combined bearings.
(5) Applicable to ball bearings such as deep groove ball bearings, angular contact ball bearings, etc. are equivalent to Classes Normal, 6, 5, 4, and 2 respectively.
