About ANSI Duplex Roller Chain


Double strand short pitch roller chains are used where increased strength is required, while smaller pitch roller chains are used. Our inventory ranges from ANSI sizes #25-2 to #240-2. A #50-2 double strand roller chian is "double" the strength of an ANSI #50-1 single strand roller chain. CTS double strand roller chains will impress you with its industry-leading tensile strength and coefficient of performance. We have the right ANSI duplex roller chains for your application. In addition, we offer corrosion resistant duplex roller chains such as stainless steel chains, nickel plated chains, coated chains, and multi-strand chains.

For quotation or other information on ANSI duplex roller chains, please contact us and we will be happy to help you.
