Patent ID: 8430801

Claim:
A conveyor roller comprising: a) a one-piece integral body having a cylindrical shape, the entirety of the body being formed solely out of a single piece of polymeric material, said body having a length extending from a first outermost end to a second outermost end and a diameter, the first outermost end of the body defined by a first outwardly protruding portion that protrudes longitudinally from a first intermediate end to the first outermost end thereby defining a first exterior shoulder between the first outermost end and the first intermediate end, the second outermost end of the body defined by a second outwardly protruding portion that protrudes longitudinally from a second intermediate end to the second outermost end thereby defining a second exterior shoulder between the second outermost end and the second intermediate end; b) said body defining an aperture extending longitudinally along and through the center of said body from the first outermost end to the second outermost end, the aperture sized to rotatably receive an axle therethrough; c) said body also defining a plurality of internal bores that extend longitudinally parallel to the aperture extending through the center of said body, the plurality of internal bores each radially spaced evenly about the aperture extending through the center of said body, the plurality of internal bores extending through at least one of the first intermediate end and the second intermediate end of said body; and (d) a cover for closing at least one of the first intermediate end and the second intermediate end of said body through which the plurality of internal bores extend through; (e) wherein the aperture extending longitudinally through the center of the body defines at least a portion of a self-lubricating bushing that is formed by the one-piece integral body.
