Abstract
A two-material hinge pin for hingedly interconnecting consecutive rows of belt modules together into a modular plastic conveyor belt. The hinge pin includes an interior rod surrounded by an outer tube. The interior rod is made of a rigid material, such as acetal, nylon, polypropylene, PVC, or steel. The outer tube is made of urethane, which provides inherent abrasion resistance in contact with the belt modules and is especially effective in abrasive environments.
