Wind power generation is rapidly spreading around the world as a clean energy source that does not generate carbon dioxide that can cause a greenhouse effect.

Large-scale wind turbines (windmills) are giant machines. Many 2MW-class wind turbines are currently under construction. The windmill blades are about 40 meters long, the height of the rotating shaft is 60 to 100 meters, and the total weight is no less than 200 tons. Therefore, the bearings used in windmills must also be large, with an inner diameter ranging from 100 mm to 700 mm. Some models require bearings with an inner diameter of nearly 2 meters. There are only six manufacturers in the world that can stably supply such large bearings to the market.

The wind turbine industry is now an industry that develops on a global scale. Therefore, in addition to bearing manufacturing, it is important to carry out marketing activities and technical services at major sites around the world.
