ABSTRACT:
A method of forming sheet metal housing for a spherical outside diameter ball bearing by forming in a sheet metal collar an inside surface conforming to half the outside surface of the bearing, placing the bearing in the housing, and hydraulically pressing a die at a predetermined pressure on the outside of the collar to conform the rest of the collar to the bearing surface, so that a predetermined torque resistance by the resulting assembly is obtained.
