50 poly steel roller chain is a 0.625" pitch ANSI roller chain made with polymer (plastic) roller links and stainless steel pin links! This combination creates a low-noise, lube-free, and clean roller chain capable of operating within abrasive and corrosive environments ranging in temperature from -200F to +180F. Our 50 poly steel chain directly interchanges with other brands and is recommended to operate on stainless steel or plastic sprockets. Each component is precision machined for improved wear life and performance, and due to the combination of metallic and non-metallic materials, this chain can consistently operate with 154 pounds of working load applied to it (higher than a complete plastic chain). 50 poly steel chain is found in applications like scientific equipment, medical equipment, food processing, space equipment, and more! We typically supply 50 poly steel roller chains in 10ft lengths, including one connecting link for connecting the chain. For alternative lengths or more information on our premium 50 poly steel chain, contact our customer support team, and we will be happy to assist you!
