INTRODUCITON

Precision, Durability, and Reliability for Onshore and Offshore Wind Farms

At aokai, we bring decades of manufacturing expertise to the wind power sector. Wind turbines are subjected to unpredictable wind gusts, immense dynamic loads, and corrosive offshore environments. A single bearing failure can lead to catastrophic downtime and exorbitant replacement costs.

Our comprehensive range of wind turbine bearings is meticulously designed using advanced metallurgy, state-of-the-art sealing technologies, and rigorous testing protocols to ensure 20+ years of reliable service life.

Industry Challenges

Conquering the Harshest Environments in Wind Energy

Wind farm operators face unique mechanical challenges. Our engineering team understands the exact pain points of the wind energy sector and designs solutions to overcome them.

Wind gusts create fluctuating axial and radial loads. If bearings lack structural integrity, premature wear and micropitting will occur.

From freezing onshore tundras to highly corrosive offshore saltwater environments, wind turbine components are constantly under attack.

Replacing a main shaft or gearbox bearing requires heavy cranes and massive logistical effort, costing hundreds of thousands of dollars.

We integrate specialized anti-corrosion coatings, custom surface treatments, and advanced raceway geometries to distribute stress evenly, ensuring our bearings thrive where standard components fail.

Core Applications

Comprehensive Bearing Solutions for Every Wind Turbine System

We provide a full spectrum of specialized bearings tailored to the specific mechanical demands of each critical wind turbine subsystem.

Pitch Bearings (Blade Bearings)

Responsible for adjusting the angle of the turbine blades to optimize wind capture. These bearings face high bending moments and vibration. Our slewing ring bearings feature localized induction hardening and robust sealing to prevent grease leakage and moisture ingress, ensuring smooth, precise pitch control.

Yaw Bearings

Located between the nacelle and the tower, yaw bearings ensure the turbine consistently faces the wind. We manufacture large-diameter, highly durable yaw bearings capable of supporting the massive weight of the nacelle while withstanding extreme storm-force loads.

Main Shaft Bearings

The heart of the turbine's rotor system. Our spherical roller bearings and tapered roller bearings are engineered with optimized internal geometries to accommodate severe axial loads and shaft misalignments, transferring rotational energy seamlessly to the gearbox.

Gearbox & Generator Bearings

Operating at high speeds, these bearings require low friction and exceptional thermal stability. Our cylindrical roller bearings and deep groove ball bearings utilize ultra-clean steel and precision-machined cages to prevent smearing, reduce noise, and prevent electrical erosion (via optional ceramic coatings).
