Jiangsu Rongfa specializes in manufacturing gear drive shafts, widely used in wind turbine gearboxes, industrial reducers, mining machinery transmission systems, metallurgical equipment, and heavy construction machinery. As core components for power and motion transmission, gear drive shafts require excellent torsional strength, fatigue resistance, and dimensional stability. With integrated capabilities in forging, heat treatment, machining, and inspection, all products undergo rigorous NDT and dimensional inspection, supported by a full-process quality traceability system. Products are widely applied in wind turbines, rolling mill equipment, cement mills, tunnel boring machines, mine hoisting equipment, and large cranes, serving high-end transmission equipment manufacturers with high reliability and long service life.
