A novel paint roller "cage" having improved tracking and ease of use is adapted for receiving different length axle shafts of various sizes of paint roller frames. An outer tubular support, upon which a paint roller cover or other paint absorbing material may be mounted, contains a pair of support bearings secured at either end of an inner tubular chassis, with one support bearing at a first end of the outer tubular support, and the other support bearing at approximately its mid point The two support bearings are connected by an inner tubular chassis, which both maintains the two bearings at a desired axial spacing and also holds the walls and radial bearing surfaces of a bushing chamber that is integrally molded with each support bearing in proper position about a tubular bushing that is adapted to be frictionally secured to the axle shaft. In one embodiment, the outer tubular support has a diameter of about 1" and a length of about 9", and can be used with both 6.5" and 9" roller frames. The nominal axial clearance between the tubular bushing and the adjacent radial bearing surfaces of the bushing chamber is less than about 0.005".
