Pitch bearing

Rotor hub and pitch bearing without mounted rotor blades

The pitch bearing, also named blade bearing, is a component of modern wind turbines which connect the rotor hub and the rotor blade.[1] The bearing allows the required oscillation to control the loads and power of the wind turbine. The pitch system brings the blade to the desired position by adapting the aerodynamic angle of attack.[2] The pitch system is also used for emergency breaks of the turbine system.[3]
