Thin-walled bearing bushings produced in the drawing process

Thin-walled bearing bushing produced in a drawing process for the support of pins in universal joints, consisting of a cylindrical sleeve section and a bottom section of nominal thickness which closes this cylindrical sleeve section on one axial end whereby a peripheral rim with a small cross sectional radius is formed between the outside surface of the sleeve section and the outside surface of the bottom section, and means defining a circumferentially extending groove in the one surface of the bottom section disposed radially inward of the peripheral rim adjacent the juncture of the sleeve and bottom, said groove being deep with respect to the nominal thickness of said bottom and having a sharp profile and axially impressed during drawing in said one surface as to reduce the wall thickness of the bottom section and to displace construction material outward into the area of the peripheral rim between the bottom section and the sleeve section of the bearing bushing, the material in the area of the peripheral rim being uniformly compressed.
