Abstract: 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.

The lithium complex greases are characterized in that base greases containing a base oil, a fatty acid having 12 to 24 carbon atoms, a dicarboxylic acid having 4 to 12 carbon atoms and/or a dicarboxylic acid ester and a lithium hydroxide are thickened with a phosphate ester and/or a phosphite ester. A method of producing the lithium complex greases is characterized in that the base greases having the above composition are added by the phosphate ester and/or the phosphite ester, and thickened under a reaction at a temperature of more than 210.degree. C. (410.degree. F.).
