Limits for chamfer dimensions

To prevent the improper dimensioning of fillets on associated components for rolling bearings and to facilitate the calculation of retaining ring location arrangements, the maximum chamfer limits for the relevant minimum chamfer dimensions provided in the product tables can be found in
  • Table: Chamfer dimension limits for metric radial and thrust bearings, except tapered roller bearings
  • Table: Chamfer dimension limits for metric radial tapered roller bearings
  • Table: Chamfer dimension limits for inch ball bearings and cylindrical roller bearings
  • Table: Chamfer dimension limits for inch tapered roller bearings
These limits for metric bearings conform to ISO 582:1995. The chamfer dimension limits for inch tapered roller bearings, which differ considerably from those for metric bearings, conform to ANSI/ABMA 19.2-1994.
The symbols used in the tables 2 and 3 are listed together with their definitions in the table Tolerance symbols.

Example

Which is the largest radial value (r1 max) for the chamfer of deep groove ball bearing 6211?

r1min = 1,5 mm and d = 55 mm are obtained from the product table. With rsmin = 1,5 mm and d smaller than 120 mm the table then gives r1max = 2,3 mm.
