#40 chain sprockets are already bored to size and include a keyway and 2 setscrews. Our #40 finished bore sprockets are manufactured from 1045CD (Cold drawn) carbon steel, which is a higher grade than most sprockets on the market. Finished bore sprockets are commonly referred to as a "type B" or "type BS" sprocket. All sprocket teeth are hardened to minimize wear overtime and these are finished with a black oxide to help resist corrosion. Nitroâ„¢ 40 sprockets work with any #40 ANSI roller chain.
