AN ISO 12 sprocket therefore mates with a chain with 3/4', or 19.05mm, pitch. The number correlates to pitch in 1/16' increments, expressed in millimeter units. Metric roller chain and sprockets are categorized according to ISO Standard 606. A #41 sprocket is therefore for 1/2'-pitch lightweight chain, a #120 sprocket is for 1-1/2' pitch chain, etc.īritish Standard / DIN / International Standards Organization (ISO) designations are governed by European standards committees. The number can be used to identify pitch in the following way: the first digits identify the pitch in 1/8' increments, and the last digit is 0 for standard proportions, 1 for lightweight chain, and 5 for rollerless bushed chain.

English roller chain and sprockets are categorized according to ANSI B 29.1M. The American National Standards Institute (ANSI) governs number designations for roller chain pitch. Chain weight - Specified in weight per unit length and varies with pitch and special construction techniques.Īn important environmental parameter to consider is the operating temperature.Maximum allowable load - The tension for which chain is rated to carry in running operation.Tensile strength - The ultimate failure tension load of a chain.

Important mechanical specifications to consider when searching for roller chain include: Consult a chain manufacturer on a specific application for material optimization. Many factors such as cost, environmental conditions, noise and heat generation and design horsepower transmission influence the best material choice. Common materials of construction include steel or hardened steel, stainless steel, nylon, acetal, polypropylene, and plastic or metal combination. Roller chain comes in a wide variety of metal and plastic materials. A double configuration has two chain strands, and so on. A single configuration has one chain strand. Standard configurations for roller chain include single, double, triple, quadruple, and quintuple or higher. Roller chain with an attachment type includes standard straight, standard bent, wide contour straight, wide contour bent, and extended pins.
