Plastic-bearing material is then allowed to congeal in the socket while in contact with the ball. A positioning fixture maintains the ball in the desired spaced position in the socket while also maintaining a seal between the ball and the socket housing so that the bearing material may be pressurized as it congeals.Field of SearchJoining parts for relative movement | |
