#120 Roller Chain Sprockets

120 sprockets are manufactured for 1.5" pitch ANSI 120 Roller Chains and are available in a wide array of configurations and tooth counts. Our 120 roller chain sprockets are supplied with hardened teeth as a standard for tooth counts 30 and below, are made from a high-strength steel, and are typically black oxided for corrosion resistance. We also supply a slew of custom 120 chain sprockets and can usually have them done within a day or two. For more information or to get a quote please contact us and we will be happy to assist you.
