Wind Turbine Bearing Cage

Design Principle Adopt domestically innovative structural design and proprietary surface treatment technology to enhance the corrosion resistance of materials; uniformly distributed roller clamping grooves ensure stable load transmission, and guide grooves optimize lubrication distribution, making it suitable for the complex working conditions of long-term outdoor operation of wind power equipment. Performance Characteristics Long Service Life: The fatigue life (L10) reaches 180,000 hours, which is 3 times that of traditional products. Strong Corrosion Resistance: No corrosion after 1200-hour salt spray test, and the corrosion resistance is 3 times that of traditional products. High Precision: The dimensional tolerance is ±0.002mm, which is 50% stricter than the ISO standard. High Adaptability: The maximum DN value is 1,200,000 (mm×rpm), which is 50% higher than the industry standard.

A variety of design and process collaborations achieve high performance. The core structure adopts an annular integral structure with uniformly distributed roller clamping grooves. Combined with precision forging and CNC machining integrated forming technology, it not only ensures uniform load distribution but also avoids assembly errors, achieving high-precision size control (±0.002mm). In terms of lubrication and corrosion resistance, metal cages use guide grooves to guide the uniform distribution of lubricating grease to reduce friction loss. At the same time, proprietary surface plasticization treatment and nano-ceramic coating increase corrosion resistance by 3 times, making them suitable for outdoor humid environments. In terms of stability, relying on material innovations such as iron replacing copper and polymer replacing steel, the structural strength is improved while reducing weight. Moreover, the cryogenic treatment process reduces internal stress of materials, which can ensure that the deformation is less than 0.01mm under the temperature difference of -40℃~+80℃. The synergy between materials and processes further optimizes performance: surface plasticization technology enhances the corrosion resistance of steel; nano-coating reduces the weight of aluminum alloy by 40%; engineering polymer and metal hybrid structure realizes lubrication-free characteristics, and the service life is extended in combination with the clamping groove design.
