Abstract
A method of producing a rolling bearing race provided with a continuous rupture seam along at least one area of its periphery and having a seating surface and a race for rolling elements, the rolling bearing race surface being exposed before rupture along at least a portion of the intended course of the rupture seam to high-energy radiation with the local confines transerve to the intended course of the rupture seam and during rupture the surface area exposed to radiation is subjected to tensile stress by an external force, characterized in that the seating surface (2,8) of the bearing race (1,7) is exposed to the radiation and the external force is exerted as a pressure force onto the raceway surface (3,9) along an area directly opposed to the area (6,10) of the seating surface (2,8) exposed to radiation.
