Rubber and polyurethane are broad material families, and neither has a universal service-life advantage. The result depends on compound chemistry, hardness, load, speed, heat build-up, fluids, surface finish and the actual material handling failure mode. Use the comparison below to define the application data and test evidence required before changing roller material. 1. Abrasion and Surface-Wear Performance Abrasion can reduce roller diameter, change traction and affect tracking. The wear mechanism varies with the counterface, pressure, speed, debris and compound.
