Abstract

Bearing bushing for universal joints, made of thin plate and consisting of a cylindrical sleeve and a bottom wall formed internally with the sleeve. The bottom of the bearing bushing is flat near its outer edge and is provided with several stamped areas distributed around the periphery to form crimps. The lateral surfaces of these crimps 17 preferably forming an acute angle alpha. The diameter D of the circle surrounding the outer surfaces is approximately equal to the diameter D of the lateral surface of the cylindrical sleeve. The juncture between the base surfaces of the crimps and the cylindrical sleeve 19 has a relatively large radius.
