Abstract
A conveyor roller and bearing arrangement rotatable about a pair of fixed stub axles lying between spaced side frame members includes a pair of self-aligning bearing assemblies in each end of the roller. Each bearing assembly includes an inner bearing race mounted on one of the stub axles, an outer bearing race rotatably mounted on the inner bearing race and an outer cushioning sleeve secured to the roller and outer bearing race for maintaining axial alignment between the inner and outer bearing races. A roller support assembly is positioned between the frame members to provide external support for the roller and cooperate with the bearing assemblies and stub axles to reduce the bending influence of the roller under loads.
