Abstract
A swivel connector between a hose reel and a source of product has a first body secured to the source of product and a second body secured to the hose reel. The first body has a plurality of stepped bores cooperating with various outer surfaces of the second body. A pair of non-metallic, non-corrosive bearings is disposed between two different stepped bores and two different outer surfaces with a seal ring disposed therebetween. A plastic thrust ring is disposed between a shoulder of the first body and a first surface of a thrust flange of the second body to absorb the thrust due to relative movement of the second body into the first body. The thrust flange has a second surface, which is parallel to the first surface, against which a first wear ring bears. The first wear ring has a plurality of balls bearing thereagainst on its side remote from the thrust flange. A retainer is supported on the first body and has a flange providing a surface against which a second wear ring abuts. The second wear ring also bears against the balls, which absorb the thrust due to relative movement of the second body out of the first body. The two non-metallic, non-corrosive bearings absorb the bending loads.
