Abstract
A spa jet of the type which utilizes a nozzle rotor for delivering a rotating jet of water into a spa is provided with a water-lubricated bearing for reducing frictional resistance to rotation. The rotor is supported by an inner bearing which is mounted for concentric rotation within an outer bearing in the housing. The inner and outer bearing surfaces which face each other include cylindrical side surfaces and upstream and downstream end wall surfaces defining a passage. The flow of water to lubricate the bearing surfaces is arranged to exert a net axial force that spaces at least one of the sets of end surfaces out of contact with each other to reduce friction and also lubricates and separates the cylindrical side surfaces.
