Notes (1) 2.5mm is included in the group. K ea SD S ea (3) V Cs (4) Units : μ m

(2) Applicable only when a locating snap ring is not used. Nominal Outside
Diameter
(3) Applicable to ball bearings such as deep groove ball bearings and angular contact ball bearings.
(4) The tolerances for outer ring width variation of bearings of Classes Normal and 6 are shown in Table 8.2.1. D

Remarks 1. The outside diameter "no-go side" tolerances (low) specified in this table do not necessarily apply within a distance (mm)

of 1.2 times the chamfer dimension r (max.) from the ring face.

2. ABMA Std 20-1996: ABEC1⋅RBEC1, ABEC3⋅RBEC3, ABEC5⋅RBEC5, ABEC7⋅RBEC7, and ABEC9⋅ RBEC9
are equivalent to Classes Normal, 6, 5, 4, and 2 respectively.
