This method comprises forming a notch of substantially V-shaped cross-section in the inner or outer peripheral surface of a bearing ring obliquely or in a V-direction, or forming a notch of substantially V-shaped cross-section in an end surface of a bearing ring at a predetermined angle with respect to the surface, heat-treating the bearing ring, and exerting wedge stress along the notch by a wedge type press-breaking tool.
