摘要： 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.

摘要： A two row angular-contact roller bearing having on undivided bearing ring and one axially divided bearing ring with a respective row of rolling elements rolling over each of the axial sections of the divided ring. The respective comb separator for each of the rows of rolling elements has an annular collar that projects axially toward the annular collar on the other separator. One separator annular collar is radially inclined inwardly and the other separator collar is radially inclined outwardly. The collars are so placed as to interfere, and they are sufficiently flexible as to deform and upon the collars being pushed together for causing the collars to loosely interlock sufficiently to enable one row of rolling elements and their separator to rotate with respect to the other. Elevations defined on the divided race ring sections support the axially inward sides of the rows of rolling elements. A shoulder on the divided race ring section engages the axially outward side of the row of rolling elements. In one embodiment, a radially inwardly inclined, axially inwardly projecting tapering retaining collar on one of the separators extends into a cooperating radial groove in its associated divided ring section for defining the axially inward support side for the respective row of rolling elements.
