Date Mar. 29, 1984.A linear motion ball bearing having pairs of axial bearing surfaces (4 and 4+40, 5 and 5') of a cross section of a radius of curvature which is slightly greater than the radius of the ball, formed in the opposed side surfaces of a bearing member (2) and a bearing rail (3), in which the distance (L2) between the centers of curvature of the upper and the lower bearing surfaces formed in the bearing member (2) and the distance (L1) between the centers of curvature of the upper and the lower bearing surfaces formed in the bearing rail (3) are different from each other. |
