The roller chains are hand-made, and each component is inspected during the manufacturing process. The chain's pins, rollers and bushings are heat treated for extra resistance to wear. The chain is designed for medium- to heavy-duty conveyor belt applications and is suitable for bake oven, annealing, washing, quenching, finishing, handling and sludge/chip removal installations. Standard roller chains include straight sidebars and large diameter rollers (WSR 4019 chain also is available with extra-large diameter rollers). The oversize rollers provide a rolling rather than sliding action to reduce drag load in conveyor applications.
