Chamfer dimension limits
To prevent the improper dimensioning of fillets on associated components for rolling bearings and facilitate calculations to locate retaining rings, the maximum chamfer limits (fig. 1) for the relevant minimum chamfer dimensions (→ product tables) are listed in the following tables:
The limits for metric bearings are in accordance with ISO 582:1995. The limits for inch tapered roller bearings, which differ considerably from those for metric bearings, are described in ANSI/ABMA Std. 19.2-2013, but are not standardized.
ExampleWhat is the largest radial value (r1 max) for the chamfer of a 6211 deep groove ball bearing?
From the product table, r1 min = 1,5 mm and d = 55 mm.
From table 1, with rs min = 1,5 mm and d < 120 mm, the largest radial value r1 max = 2,3 mm.
