Bearings are core components of wind turbines. Wind power bearings range from bearings for blades, main shafts and yaws, to high-speed bearings used in gearboxes and generators

Bearings for wind turbines mainly include: yaw bearings, pitch bearings, main shaft bearings, gearbox bearings, and generator bearings. Namely: pitch bearings, yaw bearings, transmission system bearings (main shaft and gearbox bearings).
