![]()
Heavy roller chains are also referred to as heavy-duty chains; what differentiates this class of chains in comparison to the standard is thicker side plates. These unique side plates provide more shock load capabilities and higher tensile strength ratings. Combined with the industry-leading Max Contour side plates on DUROCHAINs, our heavy series chains are capable of withstanding the most demanding and rugged applications in power transmission. We supply heavy series chains in simplex, duplex, and triplex strand widths in riveted or cottered configurations.
What sets DUROCHAIN heavy roller chains apart from others is our state-of-the-art features such as; solid bushings, solid rollers, through hardened pins, quad-staked rivets, and precision components. Our heavy-duty roller chains can even replace what other manufacturers might call a "super" series, or HE, K, or HK series chain. The combination of these features and utilizing the highest quality raw carbon steel materials created a genuine tier-one class of roller chain like no other. Heavy roller chains are used in applications such as; construction equipment, mixers, agricultural equipment, high-torque driver, and demanding conveyors.
