ABSTRACT:
A drawn cup needle bearing with an open end and a covered end contains multiple roller elements in a retainer or cage. The bearing is installed on a trunnion of a universal joint and has a protuberance projecting inwardly from the covered end so as to provide a bearing surface between the protuberance and the end of the trunnion. The protuberance is surrounded by an annular region which has been spring-tempered to allow the covered end to flex without cracking during installation of the bearing onto the trunnion and during normal operation.
