Summary: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. This end face has a diameter that is equal to or greater than the diameter of the radially inner edge of the annular grooves and smaller than the diameter of the radially outer edge of the annular groove.
