As a clean energy that will not produce carbon dioxide that can lead to the greenhouse effect, wind power is being rapidly popularized in various countries.

Large wind turbines (windmills) are giant machines. Many 2MW wind power generation equipment are under construction now. 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 be large, with an inner diameter ranging from 100mm to 700mm. Some models require bearings with an inner diameter of nearly 2m. There are only 6 manufacturers that can steadily supply such large bearings to the market, including. The wind turbine industry is now a rapidly developing industry. Therefore, in addition to bearing manufacturing, marketing activities and technical services at major outlets are important conditions.

Since the mid-1990s, the European windmill industry, which was facing the monopoly market position at that time, began to set foot in this field. Now, it also supplies such bearings to the United States, India, etc. Bearings have been fully recognized by users in the wind turbine market. At present, many wind turbine manufacturers use our bearings, so they are making contributions to protecting the earth's environment.

The special bearing for wind turbine is required to have high reliability. This is because the design premise of this kind of bearing is to ensure that the windmill can operate for 20 years, and the parts are not easy to replace in case of failure. (When the bearing is used tens of meters above the ground).

Therefore, bearing manufacturers are required to have a high degree of computer analysis technology, as well as excellent skills in materials and heat treatment. Sometimes, they also need to master the test evaluation technology for large bearing objects.

For all the above requirements, it has high strength in the bearing industry. In addition, we also meet the expectations of the market by constantly promoting the development of these strengths.
