Abstract

A thin-walled bearing bushing produced by deep drawing, in particular for the seating of pins in universal joints, including a cylindrical sleeve section with a bottom section closing the sleeve off on one end. One or more concentric depressions are axially pressed in the outer surface of the bottom surface near the resulting sharp peripheral edges. A plurality of indentations, displaced radially inward relative to the depressions and reducing the wall thickness of the bottom section of the bushing, are provided on the outer surface of the bottom section so that the uniform bushing inner surface will have a large axial load-carrying capacity.
