Industry Overview
Wind energy is one of the pollution-free energy sources, and as a clean and renewable energy source, it is increasingly valued by countries around the world. Wind power has advantages such as cleanliness, good environmental benefits, renewability, short infrastructure cycle, and flexible installed capacity. Wind power is an important field for the development of renewable energy, an important force in promoting energy technology progress and industrial upgrading, and an important measure to promote energy structure adjustment. The development prospects of China's new energy generation industry such as wind power are very broad, and it is expected to maintain high-speed development for a long time in the future。

Product application
Wind power generation uses wind to drive the windmill blades to rotate, and then uses a speed increaser to increase the rotation speed to prompt the generator to generate electricity. Slewing bearing is a new type of mechanical component that is gradually emerging around the world. It consists of inner and outer rings, rolling elements, etc., and is an important structure of wind turbines. Bearing steel ball products are used as rolling elements in yaw bearings of wind turbines and large slewing bearings of pitch bearings.
