DUROCHAIN Double Capacity Roller Chain
Made for the most demanding lifting applications within the roller chain industry, double-capacity series chains possess the capabilities to operate in applications surpassing standard roller chains' loads and torque. They are uniquely designed with double the amount of side plates, favoring that of a leaf chain, but with rollers! In addition, the design allows the chain to operate on standard simplex chain sprockets with loads that favor a duplex chain; this also gives the chain more application dynamics due to the narrower profile. What sets the DUROCHAIN double-capacity chains apart from the rest is our innovative features coupled with the best quality raw steel components. Our DC series chains are supplied with unique quad-staked rivets, solid rollers, solid bushings, through hardened pins, and max-contour side plates. The combination of which improves performance, load ratings, and overall durability. Discover the difference today when you utilize DUROCHAIN double-capacity roller chains!
