The distance between pin centers is called the pitch. The pitch is what categorizes the size of the chain & sprocket. The larger the pitch, the higher the load rating. Chain & Sprockets with small pitches carry smaller loads, operate more quietly, and at higher speeds. Multi-strand, small-pitch roller chain & sprockets are a good solution for high-load, high-speed applications.1240A21 sprocket is a 21 tooth steel construction A-Plate style sprocket.
