Chamfer dimensions

Minimum values for the chamfer dimensions (fig. 1) in the radial direction (r1, r3) and the axial direction (r2, r4) are listed in the product tables. These values are in accordance with the general plans listed in the following standards:
  • ISO 15:2011, ISO 12043:2007 and ISO 12044:1995 for radial rolling bearings
  • ISO 355:2007 for radial tapered roller bearings
  • ISO 104:2002 for thrust rolling bearings
The appropriate maximum chamfer limits that are important when dimensioning fillet radii are in accordance with ISO 582:1995 (→ Tolerances).
