ABSTRACT:
A radial ball bearing has a pair of bearing rings each of which has at least one raceway groove with a certain radius of curvature in an axial direction and a shoulder of the raceway groove. The raceway groove of one of the bearing rings is opposed to the raceway groove of the other bearing ring, and a plurality of balls are rotatably provided between the opposite raceway grooves of the bearing rings. Each of the bearing rings has a curved portion with a radius of curvature in the axial direction which is equal to or greater than that of the raceway groove between the raceway groove and the shoulder of the raceway groove. The curved portion extends from a point within an ellipse of contact produced at the bearing ring by a predetermined axial load and is smoothly continuous from the raceway groove, the point making an inflection point between the raceway groove and the curved portion.
