In 2025, global Offshore Wind Turbine Main Bearing production reached approximately 3,000 units, with an average global market price of around USD 350,000 per unit.

The gross profit margin of major companies in the industry was approximately 22%–38%.

In 2025, global production capacity was approximately 4,000 units.

An Offshore Wind Turbine Main Bearing supports the rotor shaft and transfers aerodynamic loads to the drivetrain and nacelle structure. It must withstand high radial, axial, and overturning loads under corrosive offshore conditions. Products include spherical roller, tapered roller, and large double-row bearing structures. The scope excludes gearbox bearings, generator bearings, yaw and pitch bearings, complete main-shaft assemblies, lubrication systems, and onshore-only bearings.

The industrial chain includes upstream bearing steel, forgings, rollers, cages, seals, lubricants, coatings, and condition-monitoring sensors. Midstream covers structural design, forging, heat treatment, precision machining, grinding, assembly, coating, inspection, and fatigue testing. Downstream applications include fixed-bottom and floating offshore wind turbines, drivetrain manufacturers, turbine manufacturers, wind-farm operators, and maintenance service providers.
