Abstract: In a non-machining method for manufacturing a solid-bottomed or internally flanged bearing race, especially for rolling contact bearings, the starting material is in the form of a band. For the economical manufacture of this bearing race with an annular groove of extremely precise cross-sectional shape which reduces the wall thickness of the bearing race, and which is situated at the transition from the bottom or flange portion to the race portion, a flat roundel is first stamped from the band. Then a concentric annular groove is worked into one of the planar surfaces of the roundel, while the opposite planar surface thereof is supported on a planar supporting surface. Lastly, the roundel is deep-drawn in a die to form a bearing race having a solid bottom. The end face of the drawing punch concentrically engages the roundel's planar surface that is encompassed by the annular groove.
