Industrial Rfg C3290S Chain Sprocket

Industrial Rfg C3290S chain sprocket is a bore-to-size, single-strand #50 chain sprocket with 25 teeth and a finished 1-7/16 in bore, designed for shaft mounting with a keyway and setscrews. It operates on a 5/8 in (0.625 in) pitch chain and has an outside diameter of approximately 5.322 inches, with each tooth about 0.343 inches thick to match a #50 roller chain. The bore is finished for a precise shaft fit and includes a keyway plus setscrew retention to secure the sprocket during use. Made from steel, this sprocket provides durable performance for industrial power transmission and conveyor drives that require a 25-tooth, 50-pitch solution with a 1-7/16 in shaft bore.
