Rolling bearings - Single-row cylindrical roller bearings - Chamfer dimensions for loose rib and non-rib sides
1 Scope
This Standard specifies the minimum chamfer dimensions for loose rib and non-rib sides of single-row cylindrical roller bearings of diameter series 0, 2, 3, and 4 (except dimension series 24) as specified in ISO 15. Indication is given for those minimum chamfer dimensions that are identical to those in ISO 15.

5 Dimensions
Chamfer dimensions for loose rib and non-rib sides of cylindrical roller bearings of diameter series 0, 2, 3, and 4 are given in Table 1.
The values given in Table 1 are valid for cylindrical roller bearings of standard design and E-design.
Note: For radial cylindrical roller bearings, the E signifies that they are of the design having reinforced roller and cage assembly and increased radial load-carrying capacity.
