This product is a helical cylindrical gear. Its manufacturing process includes preparing blanks from alloy steel, rough machining via hobbing or shaping, heat treatment (carburizing and quenching / induction hardening) for strength enhancement, precision finishing through shaving, honing or grinding, and final processing of the bore, keyway and flaw detection. Featuring smooth transmission and high load capacity, it is widely used as a core power transmission component in industrial gearboxes, automotive transmissions, general machinery and high-precision equipment.
