SENQCIA Inspire Series SBR “HE” Series riveted roller chain is manufactured in accordance with the ASME/ANSI B29.1 American roller chain standard. These solid bushing/solid roller chains offer exceptional performance and long life in a wide variety of applications. The link plates of the “HE” series are one size thicker than standard roller chains and the pins are through hardened and produced from special alloy steel for increased strength and shock load capacity. Solid cold forged bushings extend chain wear life and greatly reduce break-in wear. Packaged chains are pre-lubricated with high quality wax-type grease and come with a necessary connecting link to join the ends. Offset links (used to shorten or lengthen a chain strand by 1 pitch) are also available and sold separately. This chain is packaged in a 10ft box.
