Lingyuan Technology Successfully Develops 10-MW Wind Power Main Bearing Sample

On March 26, it was learned from Lingyuan Technology Co., Ltd. that the company has made significant progress in the field of high-end bearing technology—successfully developing a 10 MW wind turbine main bearing prototype. This achievement marks a crucial step forward for the company, expanding from its core business of tunnel boring machine cutters into the field of core wind power components.

As a core component of the wind turbine's transmission system, the main bearing is located at a critical connection between the main shaft and the gearbox, and its performance directly affects the unit's operating efficiency and lifespan. This wind turbine main bearing is a core support component specifically designed for large wind turbines with a power output of up to 10 MW, showcasing the technological level of high-end equipment manufacturing. A 10 MW wind turbine can generate 10,000 kWh of electricity per hour at full capacity. Based on an average household's monthly electricity consumption of 200 kWh, one hour of operation would be enough for a family's electricity needs for more than four years.

For a long time, the technology in the field of 10 MW wind turbine main bearings in China has been monopolized by foreign industry giants. While several Chinese companies are capable of independently developing and producing such bearings, this has not yet become widespread. Against this backdrop, Lingyuan Technology has successfully developed a 10-megawatt-class domestically produced bearing, which will significantly promote the process of domestic substitution.

Wind turbine main bearings have extremely stringent requirements for material performance and manufacturing processes. Leveraging its years of experience in material research and precision machining in the high-end equipment manufacturing field, Lingyuan Technology has overcome a series of key technologies, including isothermal homogeneous forging and vacuum heat treatment carburizing technology. By optimizing material purity and the uniform gradient smoothness of the carburized layer, the stability and consistency of the bearing have been significantly improved, enabling it to meet the operational requirements of high-power units with a service life of over 20 years and offshore wind power.

While accelerating technological breakthroughs, the company is actively expanding industrial cooperation. Earlier this year, Lingyuan Technology completed technical cooperation with leading wind turbine manufacturers such as Goldwind Technology and Dongfang Electric, and is advancing strategic cooperation with leading global gearbox manufacturers such as Nanjing High Speed Gear and Delijia, accelerating the process from prototype to industrialization through resource integration and technology sharing.

The successful development of this 10 MW wind turbine main bearing prototype fully demonstrates the company's strong capabilities in high-end bearing technology, providing a solid technical guarantee for the development of my country's wind power industry towards higher power and higher efficiency. Company representatives stated that they will continue to increase R&D investment to promote breakthroughs in the application of high-end bearing products in the wind power sector.
