摘要： An outer ring 3a is formed so as to have a large thickness and the pitch circle diameters Dp of balls 6 are shifted to the inside diameter side of the present ball bearing. The radiuses of curvature Ro, Ri of the section shapes of an outer ring raceway 2a and an inner ring raceway 4a are increased with respect to the diameter Db of the balls 6. At the same time, the diameter Db of the balls 6 and the thickness of an inner ring 5a are not set excessively small to thereby be able not only to prevent Brinell impressions from being formed in the outer ring raceway 2a but also to prevent the inner ring 5a from being damaged or cracked.

摘要： The pocket surface of a pocket with a ball stored therein has a pair of first pocket surfaces respectively formed inside a pair of pawls and a second pocket surface situated between the two first pocket surfaces. The second pocket surface is formed as a spherical-shaped concave surface having a radius of curvature the center of curvature of which is the rotation center of the ball in a no-load state. Each of the first pocket surfaces has a center of curvature shifted from the center of curvature of the second pocket surface toward the opposite side to the entrance (opening) of the pocket by an axially shifting quantity h1, and each of the first pocket surfaces is formed, starting from the present center of curvature, as a spherical-shaped concave surface with its radius of curvature set larger than the radius of curvature of the second pocket surface.
