ABSTRACT:
One or more of the rollers of a gravity rollerway conveyor has an annular outer tire forming the load support surface, which tire is assembled on the hub of the roller by first being turned inside out from its normal relaxed position and then being stretched over the hub that has a larger outer diameter than the tire inner diameter, so that the tire is pretensioned at its outer surface and precompressed at its inner surface to result in a significant decrease in the rolling resistance at substantially zero speed over a wide range of load values. The assembled tire has a central inner flange clamped in complementary recesses in the hub halves to prevent tire rotation.
