Note (1) The locating snap rings and snap ring grooves of these bearings are not specified by ISO.

Remarks 1. The dimensions of these snap ring grooves are not applicable to bearings of dimension series 00, 82, and 83.

2. The minimum permissible chamfer dimension rN on the snap-ring side of outer rings is 0.5mm. However, for

bearings of diameter series 0 having outside diameters 35mm and below, it is 0.3mm.
