Bearings for Wind Turbine Gearboxes

Wind turbine gearboxes operate under extreme mechanical loads, changing wind conditions, and continuous 24/7 duty cycles. High-quality bearings are essential to ensure reliable power generation, long service life, and minimal downtime. We supply a complete range of bearings designed specifically for wind turbine gearboxes, meeting the highest requirements for durability, precision, and performance.

Why Wind Turbine Gearbox Bearings Matter

The gearbox is one of the most critical components in a wind turbine. Its bearings must withstand:

• Very high radial and axial loads
• Slow and irregular rotation at the input shaft
• High-speed rotation at the output shaft
• Constant vibration and torque fluctuations
• Harsh environmental conditions (temperature, humidity, salt air)

Using the correct bearing type dramatically reduces maintenance costs, improves turbine efficiency, and prevents unplanned outages.

Available Bearing Types

We provide all essential bearing types used in wind turbine gearbox assemblies:

• Tapered Roller Bearings – for high-combined loads and long service intervals
• Cylindrical Roller Bearings – for high radial load capacity and precise shaft guidance
• Spherical Roller Bearings – for misalignment compensation and extreme load conditions
• Angular Contact Bearings – for high-speed stages and accurate positioning
• Thrust Bearings – for handling heavy axial loads

Typical Applications in Wind Gearboxes

Our bearing solutions cover all gearbox stages, including:

• Main shaft bearing positions
• Planetary stage supports
• Intermediate shaft assemblies
• High-speed output shafts
• Generator-side connections

Key Advantages

• High load-bearing capacity
• Long service life under fluctuating loads
• Optimized materials and heat treatment
• Low friction for improved efficiency
• Reduced risk of micropitting and wear
