A conveyor roller and bearing arrangement rotatable about a fixed axle lying between spaced side frame rails includes a pair of self-aligning bearing assemblies in each end of the roller. Each bearing assembly includes an inner bearing race fixed to the axle, 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.
