5 Boundary dimensions
Boundary dimensions for radial bearings of the diameter series 7, 8, 9, 0, 1, 2, 3 and 4 are given in Tables 1 to 8.
The chamfer dimensions given in Tables 1 to 8 do not always apply to:
⎯ the groove side of bearing rings with snap ring groove; these are specified in ISO 464;
⎯ the loose rib and the non-rib sides of cylindrical roller bearing rings; the exceptions are specified in ISO 12043;
⎯ the non-thrust side of angular contact bearing outer rings; these are specified in ISO 12044.
Chamfer dimension, r, applies at the corners indicated in Figure 1 and is specified with r s min in Tables 1 to 8.
The chamfer dimensions for inner rings of bearings with tapered bore may be smaller than those shown in Tables 1 to 8.
The corresponding largest single chamfer dimensions to the r s min dimensions in Tables 1 to 8 are given in ISO 582.ISO 15 pdf download.
