ANSI roller chain is a line of chain that's manufactured to ANSI B29.1 industry standards for cross compatibility between brands. ANSI is an acronym for "American National Standards Institute" that was started to help develop standards for products & services across many industries. Nitro™ ANSI chains are always manufactured to conform to ANSI B29.1 dimension & standards and to exceed the minimum strength requirements. The ANSI size chains come in various types that suite many different applications ranging from standard drives to high-load drives. The types of ANSI chains handle are standard, cottered, heavy series & super premium. We stock a full line of single, double, triple & quadruple strands for each chain type offered.
Standard ANSI chains are the most basic and conventional style roller chain used. Standard roller chains are a riveted style roller chain that comes in single, double, triple & quad row.
These cottered chain are exactly that same as standard roller chain except one side of the chain uses cotter pins. Cottered chains are much easier to work with especially on large pitch chains since cutting down the chain does not require grinding the pin head.
Heavy series chains are stronger than our standard chains and the added strength is achieved by using thicker link plates. This improves the strength & fatigue resistance for drives with moderate shock loads or with frequent starting/stopping actions.
Super premium (SP) chains are made for drives that demand extremely tough chain! Super premium chains are made from a higher quality material, hardened pins, wide waist link plates & quad staked pins. Not many drives require super premium, but if it does Nitro SP chain has you covered.
