Abstract
An improved swivel joint capable of high pressure service for rotatably connecting two conduits. The swivel joint includes an inner conduit and an outer conduit which are secured together by means of ball bearings. In addition to the ball bearings, there exist wear pads to assist the ball bearings in carrying the load should the ball bearings or bearing races become worn. Additionally, the bearing races and wear pad contacting surfaces are hardened to provide the swivel joint with extended life. The unique design of the swivel joint allows it to be safely used in high pressure service.
