Industrial SS50B18 Stainless Steel Roller Chain Sprocket

Industrial SS50B18 Stainless Steel Roller Chain Sprocket is an ANSI Type B sprocket designed for No. 50 roller chain (5/8 in pitch), featuring 18 teeth and a 1-inch bore. Manufactured in stainless steel, this sprocket offers corrosion resistance for use in environments where moisture or chemicals are present and long service life is valued. It is intended for single-strand drives and matches standard ANSI No. 50 chain geometry for reliable engagement with the chain pins and rollers. A 50B18-1 finished-bore variant is available, providing a precise 1-inch bore with a keyway and two setscrews to secure the sprocket to a shaft, ensuring proper alignment and transfer of torque. The combination of 18 teeth and the 1-inch bore yields a compact gear ratio suitable for power-transmission applications in equipment such as conveyors and processing lines that require durable, low-maintenance performance in stainless steel construction.
