Abstract:
Provided is an angular contact ball bearing that can have a load capacity increased by increasing the diameter of each ball and that is suitably used mainly to bear a thrust load. In the angular contact ball bearing, a plurality of balls are rollably interposed between an inner ring raceway groove formed on an outer peripheral surface of an inner ring and an outer ring raceway groove formed on an inner peripheral surface of an outer ring. The plurality of balls are retained by a plurality of separator retainers that are interposed between the adjacent balls and that are spaced apart from each other. A contact angle θ of each ball is within a range of 45° to 65°.

Claim (Index 1):
An angular contact ball bearing comprising:\n an inner ring having an outer peripheral surface formed with an inner ring raceway groove; an outer ring having an inner peripheral surface formed with an outer ring raceway groove; a plurality of balls rollably interposed between the inner ring raceway groove and the outer ring raceway groove; and a plurality of separator retainers configured to retain the plurality of balls, the separator retainers being interposed between the adjacent balls and that are spaced apart from each other, wherein a contact angle of each ball is within a range of 45\u00b0 to 65\u00b0.
