A polyurethane conveyor roller end cap internally houses rolling bearing and externally is interference-fitted into an end of a roller tube. The outside surface of the body of an end cap, although arranged in large part to engage the tube, has provided therein a circumferential line of blind recesses designed to minimize the amount of polyurethane used for the end cap while still allowing for the provision of load bearing column of polyurethane. |
