Planetary Gear｜Core Components for Wind Turbine Transmission Systems The planetary gear revolves around the central sun gear while simultaneously rotating on its own axis. Through its meshing with the outer ring gear, it enables the transmission of...
Ring rolling forms seamless metal rings by continuously rolling heated blanks in a circular direction. This technique aligns the metal grains along the ring, improving strength, toughness, and fatigue resistance. It is commonly used for Bearing Rings, gear rings, planetary gears, sun gears, shrink discs, and forging wheels. Depending on the application, these rolled blanks can undergo heat treatment—such as normalizing, quenching, tempering, or annealing—to optimize mechanical performance and ensure long service life.
At Jiangyin Liaoyuan Equipment Manufacturing Co., Ltd., we specialize in producing high-quality seamless forged rings using advanced hot ring rolling technology. Our integrated production process—from raw material selection and heating to ring rolling and rough machining—ensures superior structural integrity, fatigue resistance, and traceability.
After rolling, the blanks can be further processed in-house through rough or Precision Machining, providing a solid foundation for high-performance components and a seamless transition to our Machined Rings category, where precision-finished counterparts are delivered for demanding industrial and heavy-duty applications.
We offer custom radial profile rolling for T-shaped, L-shaped, and other non-standard cross-sections, which delivers:
Partner with Liaoyuan to secure ring rolled forgings that provide strength, durability, and traceable quality.
