To achieve a dependable axial fastening of a flat cylindrical outer surface of the outer ring of a double row angular anti-friction bearing inside the smooth internal surface of the bore of the external housing in which the outer ring is disposed, the races for the bearing rolling elements, and which are either balls or tapered rollers, are oriented so that the resultant lines of bearing force extend from the rolling elements, converge and intersect the outer surface of the outer ring. The resultant lines of force converge at or radially outward of the outer surface of the outer ring. A respective pair of interruptions, in the form of annular grooves around the outer surface of the outer ring, and having sharp transition edges with the outer surface of the outer ring, are defined at both axial sides of and near to the intersection of a resultant line of force with the outer surface of the outer ring. Where the lines of force are near each other where they intersect the outer surface of the outer ring, one pair of interruptions are provided for both resultant lines of force. Each pair of interruptions near to and alongside one of the resultant lines of force or a single pair of interruptions near to and straddling both lines of force between them define a cylindrical section of the outer surface of the outer ring, which the resultant lines of force intersect.
