Wind turbine bearings are core components of wind power generation systems, operating in extreme environments with high maintenance costs, and requiring exceptional durability and reliability. As wind power is a vital renewable energy source, its development heavily depends on the support of high-performance bearings. The main bearings in wind turbines include yaw bearing assemblies, main shaft bearings, gearbox bearings, and generator bearings, with structural types covering four-point contact ball bearings, crossed roller bearings, cylindrical roller bearings, spherical roller bearings, and deep groove ball bearings. Among these, large yaw bearings and main shaft bearings present significant technical challenges, relying heavily on imports for a long time. These are critical bottlenecks for the localization of wind turbines. Achieving localization of wind turbine bearings will not only enhance the design and application level of the domestic bearing industry, narrow the gap with international standards, and promote technological progress in the industry, but also effectively reduce wind power costs and accelerate the development of China's renewable energy sector.

Wind turbines operate year-round in harsh outdoor environments, enduring significant variations in temperature, humidity, and load, with wind speed peaks reaching up to 23 m/s and impact loads present. Therefore, wind turbine bearings must feature excellent sealing and lubrication performance, impact resistance, longevity, and high reliability. Wind turbines need to start and track wind direction changes at low wind speeds , requiring bearing structures to be specially designed for low friction and high sensitivity. Large yaw bearings often require gear teeth on the outer ring. To ensure optimal turbine operation, the design, material selection, manufacturing process, lubrication solutions, and sealing technology of bearings all need targeted research and development to significantly improve equipment performance and reliability.

Since turbines are often installed in hard-to-access areas such as mountains, deserts, and coastlines, system maintenance is critical. Condition monitoring systems can effectively track the performance of the drivetrain, while predictive maintenance enhances system reliability and efficiency, increasing effective operating time. Technologies such as vibration analysis, oil analysis, and infrared thermography can accurately determine the optimal maintenance timing. Predictive maintenance strategies significantly enhance operational reliability by implementing repairs only when necessary, avoiding over-maintenance, and reducing costs.
