Abstract
A swivel joint has uniform ball bearing requirements for all bearing races. The swivel joint has a male connector and a female connector that coaxially interconnect and swivel relative to each other. Each connector has three bearing races to form three sets of bearing races, each of which supports that same number of ball bearings. The circumference of the main set of races are enlarged by less than the diameter of one ball.
