  • Publication number: 20120251025
    Abstract: An angular contact ball bearing, which has an outer ring, an inner ring, and a plurality of balls arranged between the outer ring and the inner ring in a cage rotatably about a bearing axis. The cage is guided via a cage guiding surface of the outer ring. The angular contact ball bearing has a nominal pressure angle of less than or equal to 30 degrees. In a sectional view, a circular arc runs from a point of a track of the outer ring furthest away from the bearing axis along the track in the direction of a track end facing the cage guiding surface to an intersecting point of the circular arc a straight line through the cage guiding surface has a central angle that is greater than or equal to 60 degrees.
