ANSI Industrial Roller Chains

ANSI roller chain is the most widely used power transmission chain in the U.S. market. Nitro ANSI roller chain is fully compliant to ANSI B29.1 industry standards. On average Nitro Chain is 23% stronger than the minimum ANSI requirements. There are 4 different ANSI chains to choose from, which are standard, cottered, heavy duty and super premium. All ANSI chains are available in single and multi-strand options. Nitro Roller Chains have a reputation for being a tough, durable and reliable chain product that will keep your machines running! View our roller chain size charts for easy comparison of the specifications between all chain sizes.

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 roller chain is a large step up from the heavy duty version. The super premium chains are made from an carbon and alloy steel, thru-hardened pins, wider waist link plates and quad staked pins. The heavy duty roller chain is made with carbon steel, 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. In most cases the super premium is not necessary, but is available for those limited applications that require its strength.
