PROBLEM TO BE SOLVED: To provide an angular contact ball bearing capable of being used only with radial load though it is the angular contact ball bearing.SOLUTION: In an angular contact ball bearing in which a ball 106 is kept into contact with raceway surfaces 102a, 104a of an inner ring 104 and an outer ring 102 at four points in a typical constitution, shoulder portions 102b, 102c, 104b, 104c are formed at both sides of the raceway surfaces of the inner ring and the outer ring, and contact angles θ1, θ2 to 0° of two straight lines L1, L2 passing through opposed contact points are determined that the contact angle θ1 is 0°-5°, and the contact angle θ2 is 35°-45°, when an angle vertical to an axis is 0°.SELECTED DRAWING: Figure 1 |
