6、o which the bearings are tted, the chamfer dimension limits, of which the minimum values are of primary interest to the bearing designer and user, need to be specied. These limits are of relevance for cross reference pur-poses.This standard does not apply to chamfers for which dimensions are not spe

10、ction of the chamfer surface and the ring face. The axial direction chamfer dimension of a bearing ring is the distance between the imaginary sharp ring corner and the intersection of the chamfer surface and the bore or outside cylindrical surface of the ring.NOTE: The exact shape of the chamfer sur
11、face is not specied, but its contour in an axial plane shall not be allowed to project beyond the imaginary circular arc of radius rs min, tangential to the ring face and the bore or outside cylindrical surface of the ring (see gure 1).Chamfer dimensions shall be as given in gures 1 to 11 and tables
