<p>PROBLEM TO BE SOLVED: To improve incorporating performance of a ball for a deep groove ball bearing having a high thrust load capacity.SOLUTION: A ball 31 is incorporated between an outer ring 11 and an inner ring 21 having different left and right shoulder heights, and the ball 31 is retained by a retainer 40. A slope shaped ball guide surface 25 is formed to improve incorporating performance of the ball 31. The ball guide surface 25 is formed at least on an outer peripheral edge of a back surface 24 adjacent to a large diameter shoulder 23b in the inner ring 21 or an inner peripheral edge of a front surface 14 adjacent to a large diameter shoulder 13b in the outer ring 11.</p> |
