PLASTIC ROLLER BEARING

A bearing made of plastic in which the outer race is made of two annular elements that define a split therebetween and are adjustably held by threaded screws circumferentially of contact rolling elements made as rollers disposed angularly spaced about a drum-like inner race. The rolling elements are held in spaced relative positions by axial or lateral projections of a retaining member that in conjunction with a ring-like retaining member holds the rolling elements in assembly. This assembly is held in an annular space defined by flanges on the inner race and is disposed circumferentially of the inner race. The inner and outer races and the rolling elements have coacting tapered surfaces that keep the rolling elements tracking accurately.
