Renewable Energy - Wind Turbine Slewing Bearings

LTZC, a professional manufacturer of slewing bearings, offers bearings in various sizes suitable for heavy machinery such as excavators, cranes, and tunnel boring machines. In wind turbines, slewing bearings are used in two critical systems — the yaw system and the pitch system, each demanding exceptional reliability, accuracy, and durability.

1. Yaw System Slewing Bearing

The yaw system adjusts the turbine nacelle to face the wind direction. The slewing bearing supports the nacelle and upper components while enabling precise rotation to keep the blades at the optimal angle against the wind. This ensures maximum wind capture, higher power generation efficiency, and system stability even under rapidly changing wind conditions.

• High static and dynamic load capacity

• Smooth rotation under fluctuating torque

• Long-term sealing and corrosion resistance

2. Pitch System Slewing Bearing

The pitch system controls the blade angle relative to the wind to optimize aerodynamic efficiency. Slewing bearings here must offer high precision and consistent torque control, allowing the blades to rotate smoothly and maintain turbine speed stability. Even in extreme weather — such as high winds, icing, or storms — the pitch bearing maintains balanced load distribution and operational safety, ensuring reliable energy output.
