Wind turbine bearings (Spherical roller bearings)

Spherical roller bearings are widely used in wind power generation equipment. These bearings are suitable for critical parts of wind turbines, such as the main shaft and gearbox. They can effectively absorb and resist shocks and vibrations, ensuring the efficient, stable, and reliable operation of the equipment.


  • Simultaneously Withstands High Radial and Axial Loads:This bearing can operate stably under high load conditions.
  • Self-Aligning Capability:Can compensate for installation errors and shaft bending, ensuring operational stability.
  • High-Strength Materials:Manufactured using high-strength materials, providing excellent wear resistance.
  • Optimized Lubrication Design:Ensures long bearing life and fatigue resistance.

This spherical roller bearing is primarily used in critical parts of wind power generation equipment, such as the main shaft and gearbox.


Common types of Wind Turbine Bearings include spherical roller bearings, cylindrical roller bearings, and tapered roller bearings. Each type, based on its design and performance characteristics, is suitable for different parts of the wind turbine, such as the main shaft, gearbox, and generator.

Maintaining Wind Turbine Bearings involves regularly checking the lubrication status to ensure adequate and clean lubrication. It is crucial to prevent contaminants from entering the bearing. Additionally, regularly inspect the bearings for wear and operational status, and promptly replace or repair any problematic bearings to ensure the turbine's continuous and efficient operation.

The lifespan of Wind Turbine Bearings depends on several factors, including load, operating speed, environmental conditions, and maintenance practices. With proper maintenance and suitable operating conditions, the lifespan of bearings can reach 20 years or more. However, the actual lifespan can vary depending on the specific application and conditions.

Common faults of pillow block bearings include wear, overheating, poor lubrication, and contamination. Preventive measures include regular lubrication, maintaining a clean working environment, regularly inspecting the bearing condition, correct installation, and avoiding overloading. Timely maintenance and care can effectively extend the bearing's service life.
