Look no further than this 40B12 sprocket that's designed with precision machining and high-quality materials. Put this durable component to the test - its hardened teeth keep the motion flowing. Because this sprocket meets ANSI standards, you can trust in its reliability over the years. Breakage and premature wear are reduced, as it makes solid contact with any #40 roller chain.
This sprocket is further enhanced with a black-oxide coating. Rust and environmental wear are no match for this coating that withstands the daily rigors on any assembly. USA Roller Chain & Sprockets is proud to offer this product as a bored-to-size sprocket. Customize it, or use the stock 1/2-inch bore instead.
