Planetary gear rings and internal gear rings are critical components in heavy-duty transmission systems, widely used in mining machinery, construction equipment, reducers, and other industrial applications. As the core of planetary gearboxes, their precision, strength, and durability directly affect equipment efficiency, stability, and service life. At our professional manufacturing base, we focus on high-precision planetary gear ring and internal gear processing to meet the strict demands of heavy machinery worldwide.
We specialize in the production of custom internal gear rings for planetary drives, using high-quality alloy steel materials such as 20CrMnTi, 42CrMo, and other hardened steels. Our full production line includes precision forging, CNC turning, gear shaping, heat treatment, gear grinding, and precision inspection. Advanced heat treatment processes, including carburizing and quenching, greatly improve surface hardness, wear resistance, and fatigue life, ensuring stable performance under heavy loads and harsh working conditions.
Equipped with high-precision CNC gear machining and grinding equipment, our machining accuracy reaches ISO Grade 5–6, ensuring excellent tooth profile, tooth direction, and runout accuracy. This high precision guarantees smooth meshing, low noise, low vibration, and reliable operation when matched with sun gears and planetary gears. We can manufacture internal gear rings with various modules, tooth numbers, diameters, and helix angles to meet customized design requirements for different heavy machinery and mining equipment.
Our planetary gear rings and internal gear rings are widely applied in mining machinery, crushers, drilling equipment, heavy-duty reducers, and construction machinery. With stable quality, high load-bearing capacity, and long service life, they help reduce downtime and maintenance costs for global customers.
We adhere to strict quality control standards throughout the production process, from raw material testing to finished product inspection. Each gear ring undergoes complete dimensional and performance testing to ensure consistency and reliability. With rich manufacturing experience, flexible production capacity, and professional technical support, we provide reliable one-stop gear processing solutions for global customers.
If you are looking for a trusted manufacturer of high-precision planetary gear rings and internal gear rings for heavy machinery, we are your ideal partner.
