Nitro® ANSI Roller Chains
From agricultural to large-scale material handling applications, we have you covered with our full selection of ANSI roller chains. Nitro® ANSI chains are built to fully conform to ANSI/ASME B29.1 standards. Our ANSI chains are manufactured and continually tested to ensure we consistently deliver a high-quality chain every time. We offer a full selection of single strand & multi-strand options for all roller chain sizes. You can depend on Nitro® Chain as your primary source for high-quality ANSI chains to keep your machines running.

What is ASME / ANSI Roller Chains?
These are chains built for the American market that are controlled by the ANSME/ANSI B29.1 standards. Manufacturers must meet set dimensions and minimum strength ratings for the chain qualify for industry compliance. This allows ANSI chains to fully interchange with other brands and compatibility with ANSI sprockets.
Standard Vs Heavy Duty Roller Chain
Standard roller chain and heavy duty roller chains mostly have the same dimensions. The main difference is that the heavy roller chains are produced with thicker inner & outer link plates. By using thicker plates, this improves the heavy duty chains working load strength and fatigue resistance. This makes the heavy duty roller chain a better choice for drives with moderate shock loads and/or frequent starting and stopping. Standard roller chain are best suited for smoother running drives that have lighter loads.
Heavy Duty Vs Super Premium Roller Chain
Super premium (SP) roller chain is a huge step up from standard & heavy duty options. In most applications this SP chain far more than what you will need for strength. This chain is enhanced by using thru-hardened pins, wider waist link plates and quad staked pins. The heavy duty roller chain is made with case hardened pins, thicker plates and dual staked pins. The advantage of the super premium is the extremely high strength to withstand extreme shock loads and drives with frequent forward/reversing direction changes.
ANSI Roller Chain Manufacturing
Manufacturing of Nitro® ANSI chains has evolved with the adoption of new techniques and improved computer controlled technology that ensures a quality product is delivered. Raw materials combined with heat treatment are carefully examined and selected for optimum strength and wear resistance resulting in a longer lasting product. During the production of roller chain components, the factory thoroughly examines parts from every batch to verify proper dimensions, consistency and material hardness is achieved.
ANSI Roller Chain Sizes
There are a total of 14 ANSI sizes that make up the entire line of ANSI chains. Most chain sizes are available in single, double, triple and quadruple strand options. We offer put together roller chain size charts to help you easily identify your chain by dimensions.
