Abstract
There is disclosed a weight transfer roller apparatus including a barrel type housing formed on one extremity with a radially inwardly projecting retaining flange forming a circular protrusion opening. A roller ball is received within the bore of such barrel, has one side projecting from such opening, and has its opposite side nested on an annular high lubricity plastic ring formed with a bearing seat defining a sector of a sphere corresponding with the spherical roller. The annular bearing ring rests on a retainer secured to such housing whereby the housing may be mounted in a weight transfer platform and loads passing thereover will weight downwardly on such ball to be carried by the bearing ring. Preferably, the ball, annular bearing ring, and retainer are telescopically received in the bore of the barrel with the retainer being selectively removable for removal of the bearing and ball for replacement thereof upon deterioration or damage.
