An outer ringis formed so as to have a large thickness and the pitch circle diameters Dp of ballsare 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 racewayand an inner ring racewayare increased with respect to the diameter Db of the balls. At the same time, the diameter Db of the ballsand the thickness of an inner ringare not set excessively small to thereby be able not only to prevent Brinell impressions from being formed in the outer ring racewaybut also to prevent the inner ringfrom being damaged or cracked.
