ABSTRACT:
A method of swaging a spherical bearing comprising a ball and a bearing housing, the method comprising: providing a ball and a bearing housing to be swaged around the ball; creating a temperature differential between the temperature of the housing and the temperature of the ball, the ball being at a lower temperature than the housing such that the relative size of the ball with respect to the housing decreases; inserting the ball in the housing; swaging the housing around the ball, the ball being cooler than the housing during the swaging process; allowing the ball and housing to return to ambient temperature such that the relative size of the ball with respect to the housing increases.
