On July 27, 2022, the "12 MW offshore typhoon-resistant wind turbine main shaft bearing" developed by HNXQ Bearing Technology Corporation, a leading large-scale slewing bearing manufacturer in China, was successfully rolled off the production line and passed the inspection of the National Bearing Quality Supervision and Inspection Center. All indicators meet user requirements.
This means that the company has successfully broken the technological monopoly of international companies in the field of high-power wind turbine main shaft bearing development, and its R&D strength has entered the world's first echelon.
The main shaft bearing of wind turbine is the core component of wind turbine, and its core technology has been monopolized by foreign bearing companies.
In 2010, HNXQ successfully developed a 2MW direct-drive wind turbine main shaft bearing, filling the domestic gap.
After that, the company successfully developed 2.5 MW, 3 MW, 3.4 MW, 4 MW, 5 MW, 6.25 MW, 7 MW wind turbine main shaft bearings, realized industrialization, replaced imports, and became a global wind power generator. A benchmark company in the bearing industry.
