National Element Inc.'s roller chains are hand made to the highest quality standards. Each component is inspected during the manufacturing process. National makes a full range of conveyor belts to provide complete chain-on-edge driven conveyor belt manufacturing capabilities. The chain's pins, rollers and bushings are heat treated for extra resistance to wear, and coarse hardness on the rollers is typically twice the depth of industry practice. Pins and bushings are milled flat, and bushings are press fit to lock them against rotation for long service life. Sidebar holes normally have flats to accommodate standard pins. National chain may be supplied with all round hole sidebars when used in through rod applications.
