Abstract:
An angular contact ball bearing includes an outer ring having an outer diameter D and a first rolling surface and an inner ring having an inner diameter d and a second rolling surface, and no more than one row of balls between the first rolling surface and the second rolling surface, each of the balls having a diameter D w . The diameter D w  of the balls, the outer diameter D of the outer ring, and the inner diameter d of the inner ring satisfy the relationship: D w > 0.7 * ( D - d ) 2

Claim (Index 1):
An angular contact ball bearing, comprising:\n an outer ring having an outer diameter D and having a first rolling surface, wherein the outer ring has first and second outer ring axial ends, a portion of the outer ring forming an outer shoulder which projects radially inwardly and forms a portion of the first rolling surface, a radially inner end of the outer shoulder forming a first axially extending radial surface having a first axial width, an inner ring having an inner diameter d and having a second rolling surface, wherein the inner ring has first and second inner ring axial ends, the inner ring forms an inner shoulder which projects radially outwardly and forms a portion of the second rolling surface, a radially outer end of the inner shoulder forming a second axially extending radial surface having a second axial width, wherein the second axial width is greater than the first axial width, the second rolling surface being curvilinear along a side of the shoulder, no more than one row of balls disposed between the first rolling surface and the second rolling surface, each of the balls having a diameter D w , wherein the diameter D w  of the balls, the outer diameter D of the outer ring, and the inner diameter d of the inner ring are chosen such that they satisfy the relationship: D w > 0.7 * ( D - d ) 2 a cage having a plurality of pockets formed by claw like extensions which extend essentially in the axial direction, each of the balls being in one of the plurality of pockets and having first and second axial ends, wherein the diameter of the balls, and the shoulder are configured that the cage overlaps the first axial end of each of the balls and the second rolling surface along the shoulder overlaps the second axial end of each of the balls such that the balls are held on the inner ring in a self-retaining manner.
