Abstract:
1. A paint roller bearing cage, adapted for receiving an axle portion of a paint roller frame, said cage comprising: a tubular outer support; an end support bearing at a first end portion of the outer support; a central support bearing in a middle portion of the outer support; a tubular inner chassis for securing the central support bearing a predetermined longitudinal spacing from the end support bearing; and a pair of tubular bushings adapted to frictionally engage said axle portion; wherein each of said support bearings further comprises an integrally molded axial bore for providing an axial bearing surface for radially constraining said axle portion, and an integrally molded bushing chamber defined by a sidewall connecting first and second radial bearing surfaces for axially constraining a respective one of said tubular bushings wherein said tubular bushings are located in respective bushing chambers; wherein said first radial bearing surface extends radially outwards from said axial bore and said second radial bearing surface is defined on an enlarged inwardly projecting lip extending radially inwards from said sidewall; and said tubular inner chassis is suspended inside said tubular outer support with an outer circumference of said semi-cylindrical sidewall in contact with an inner diameter of the tubular inner chassis and an outer diameter of the respective support bearing in contact with an inner diameter of the tubular outer support.
