Pitch bearing

About this product

The part that connects the blade to the rotor. Adjust the angle of the wing depending on the strength of the wind.

Pitch bearings connect to support the blade and rotor. By abjusting the angle of the wind depending on fhe strength of wind, power is actively controlled, and beacuse optimal power must be spent by responding to the changing wind energy, precision machinging and processing technologies are required.

Alloy steel for mechanical structures, such as 42CrMo4 (SCM440) are commonly used for bearings. The pich and yaw bearing must withstand large amunts of both static and dynamic load and momentum, while the wind power generator is operating.In addition, the yaw bearing is in charge of the soft rotation for the operation of the nacelle and the pitch bearing is in charge of active control of the blade in all wearther conditions. Furthermore, it must have resistance against corrosion and damages during its given lifetime.

Bearing materials are mainly used for mechanical structural alloy steels such as 42CrMo4 (SCM440). Pitch and yaw bearings provide a huge static, dynamic load and moment during the operation of the wind generator. You have to endure it. And, under all weather conditions, the yaw bearing rotates smoothly in the operation of the nousel, Pitch. Bearing acts as the active control of the blade, and over a given lifetime, it acts as a corrosion and damage. You have to have resistance that you can withstand.
