Abstract
A conveyor roller having a low noise level and a long wear life consisting of a steel shaft, an intermediate layer made of a polymeric material (e.g., fiberglass-reinforced polyester) bonded to the shaft, a helical steel spring wear element situated around the periphery of the intermediate layer, and an outer layer made of an abrasion-resistant polymeric material bonded to the intermediate layer and the wear element. This roller solves the problem of high noise levels in steel plants, yet also exhibits long wear life.
