Bearings for wind power applications can be classified into four main categories: main bearings, gearbox bearings, generator bearings, and pitch & yaw bearings. Among these, main bearings play a pivotal role in supporting rotor loads and transmitting torque, making this segment the core market. As wind turbine sizes continue to grow, the demand for large-diameter spherical roller bearings and tapered roller bearings has significantly increased.

For gearbox bearings, they occupy a considerable share in gearbox-driven wind turbines by utilizing multiple sets of bearings to achieve torque amplification and rotational alignment.

Bearing Demand by Turbine Type

Based on the type of wind turbine, horizontal-axis wind turbines (HAWT) dominate the global installed capacity market due to their higher efficiency and scalability, creating a highly concentrated demand for bearings. In contrast, vertical-axis wind turbines (VAWT) hold a much smaller market share.

Bearing Requirements by Installation Type

From an installation standpoint, onshore wind power leads the market in terms of revenue, benefiting from mature infrastructure and lower capital expenditures. However, offshore wind power is expected to grow at a faster pace due to the advantages of higher turbine capacities and abundant wind resources. Offshore wind applications pose particular challenges for bearings, requiring superior properties such as corrosion resistance, sealing performance, and extended lubrication lifespan.
