Bearing Solutions for Wind Turbine

Wind turbines operate in environments characterized by openness, complexity, and extreme conditions. This places stringent requirements on the weather resistance, corrosion resistance, and load-bearing capacity of core components such as bearings, gearboxes, and blades. Precise manufacturing processes and rigorous quality control are crucial to ensuring that these bearings meet the demands of the wind energy industry.

HSN Bearings focuses on providing high-reliability solutions throughout the entire lifecycle of wind turbines. We collaborate closely with leading Chinese manufacturers to offer cost-effective products and services. In response to the wind power industry’s challenges of high loads, extreme temperatures, complex alternating stresses, and high maintenance difficulty, our products fully satisfy the stringent requirements of both onshore and offshore wind power equipment. They are backed by the R&D capabilities, technical expertise, and service strengths of top-tier manufacturers.

We specialize in the R&D and manufacturing of wind turbine bearings, working in close collaboration with leading domestic manufacturers. Our products are compatible with globally renowned brands such as Vestas, Siemens Gamesa, and GE Renewable Energy. Covering main shaft bearings, yaw bearings, gearbox bearings, and generator bearings, our products feature high load capacity, impact resistance, and long service life, effectively ensuring the continuous and efficient operation of wind turbines under complex wind conditions and high loads.

Main Shaft Bearings

The main shaft bearing is one of the core components of a wind turbine, directly supporting the full load transmitted from the blades and driving the generator. The bearing must accommodate both axial and radial loads while operating stably under harsh conditions. Its key features include:

Withstanding multi-directional composite heavy loads with extremely high impact resistance;
Enduring extreme environments with stringent stability requirements;
Offering excellent fatigue resistance for continuous operation under heavy stress.

Bearing Types

Yaw and Pitch Bearings

The yaw bearing enables the nacelle to “face the wind,” while the pitch bearing controls the blade “angle adjustment.” Both must withstand complex loads in extreme environments. Their characteristics include:

Bearing multi-directional loads with extreme adaptability to harsh conditions;
A compact design that balances superior load capacity with extended service life;
Directional optimization based on dynamic load variation, significantly reducing the risk of unit failure and improving operational stability.

Bearing Types

Gearbox Bearings

The gearbox bearing handles composite loads from wind forces, gear meshing stresses, and speed variations. It also plays a key role in increasing turbine speed and converting wind energy into electricity. Its features include:

Stable load capacity under high speeds and heavy loads;
Low friction loss to ensure transmission efficiency;
A lifetime lubrication design with sealed protection to extend maintenance intervals.

Bearing Types

Generator Bearings

Generator bearings support the wind turbine generator rotor, enabling smooth, efficient, and low-noise energy conversion. These bearings must remain stable under high-speed, low-friction conditions. Their features include:

Extremely high rotational accuracy and operational smoothness;
Low noise and vibration to improve wind turbine efficiency;
Strong impact resistance and toughness to cope with dynamic load fluctuations;
Broad environmental adaptability, including tolerance for extreme operating conditions.
