272200128 2BS315.30.3-5 Internal Gear Ring | Construction Machinery & Truck Spare Parts Wheel Loader Parts SDLG XCMG

The 272200128 / 2BS315.30.3-5 internal gear ring is a key transmission component widely used in heavy-duty trucks and construction machinery. Manufactured with high-strength alloy steel, this internal gear ring undergoes precision machining, carburizing and quenching heat treatment. It features high hardness, strong wear resistance, stable load capacity and long service life. It fits perfectly with matched planetary gears in the gearbox assembly. Our gear rings are strictly dimension-checked one by one before shipment to ensure precise meshing, reduce vibration and noise during operation, and avoid early gear failure under heavy load working conditions. Suitable for heavy-load working scenarios such as mining, engineering construction and long-distance transportation. We supply this internal gear ring as OEM replacement spare parts for global buyers.
