  China plans to fully achieve the goal of "carbon neutrality" in 2060, in this context, the state attaches great importance to the new energy market, especially the wind power industry, and the development of super large, small and medium-sized wind turbines will become the main force of clean energy in the future. Hebei Shaft Research Institute knows that the bearings supported by the fan are not ordinary bearings, which should not only resist the invasion of wind and sand, but also withstand the temperature difference between high and low, humidity and heat resistance. 9 blade frame round wind turbine, each blade with 4 sets of bearings, plus the spindle, the speed of the bearing, each set to use more than 40 sets. At present, the bearing used for the fan is in the stage of research and development and trial production.

In the process of developing bearings used in the "9-blade wind turbine", Hebei Bearing Industry Technology Research Institute and Fresh Energy Technology Zhangjiakou Co., Ltd. cooperated to overcome a series of technical problems. This research and development work not only fills the international gap in wind turbine start-up and hurricane power generation, but also has great significance for achieving China's 2060 "carbon neutral" goal.

Due to the special operating environment of wind turbines, the bearings used must have extremely strong durability and adaptability. Bearings need to be able to resist the erosion of wind and sand, while resisting extreme temperature changes, humidity, high temperature and other harsh conditions. Especially for the 9-blade frame circular wind turbine, each blade is equipped with 4 sets of bearings, plus the bearings required for the spindle and the speeder, each fan needs about 40 sets of bearings.

At present, Hebei Bearing Industry Technology Research Institute is conducting research and development and trial production of these special purpose bearings. This involves material selection, design optimization, manufacturing process improvement and other aspects of technical research. Through the use of advanced material science, precision machining technology and strict quality control systems, the R&D team is committed to creating high-performance bearings that can meet the demanding requirements of wind turbines.

The success of this research and development results can not only improve the operating efficiency and reliability of wind turbines, reduce maintenance costs, but also provide solid technical support for the development of China's wind power industry, accelerate the popularization and application of clean energy, and make positive contributions to the realization of the national "carbon neutral" strategic goal.
