Martin Sprocket & Gear 5YFN6O22 Roller Chain Sprocket

Martin Sprocket & Gear 5YFN6O22 Roller Chain Sprocket is a precision-machined drive component designed for a #60 roller chain. It features a 3/4 inch pitch, 22 teeth, and a 2-7/8 inch keyed bore for secure mounting on a compatible shaft. The 5YFN6O22 designation identifies this exact configuration within Martin’s roller chain sprocket lineup, ensuring consistency with standard #60 chain drives. The 22-tooth geometry defines the sprocket’s engagement profile with the chain, influencing how it pairs with the matching drive sprocket and the overall drive ratio in your system. The keyed bore provides a torque-transmitting interface when used with a matching shaft key, helping prevent slip under load. This sprocket is built to fit drive trains that require a 22-tooth, 3/4-inch pitch sprocket with a 2-7/8 inch bore and #60 chain, offering a precise replacement or upgrade for compatible equipment.
