Wind power bearings are critical components in wind turbines, primarily applied in the main shaft, gearbox, and generator. They support massive rotor loads and endure variable wind conditions. Key types include slewing bearings for blade pitch and yaw control, and spherical roller bearings for main shafts. Their design prioritizes high durability, reliability, and minimal maintenance to withstand harsh environments and ensure efficient, long-term turbine operation, directly impacting energy output and operational lifespan. Advanced materials and sealing technologies are essential for their performance.
