As a clean energy that will not produce carbon dioxide that can lead to greenhouse effect, wind power generation is rapidly popularized all over the world. Large wind turbine (windmill) is a huge machinery. Many 2MW wind power generation equipment under construction now have windmill blades about 40m long, rotating shaft height of 60-100m and total weight of no less than 200t. Therefore, the bearings used in windmills must also be large, with inner diameter ranging from 100mm to 700mm. Some models need bearings with inner diameter of nearly 2m. These large bearings can be stably supplied to the market There are only 6 manufacturers in the world, including BLS. The wind turbine industry is now a global industry. Therefore, in addition to bearing manufacturing, it is important to carry out marketing activities and technical services in major outlets in the world. BLS began to set foot in this field for the European windmill industry which monopolized the market position at that time. Now, BLS also supplies such bearings to the United States, China and India. BLS bearings are fully recognized by users in the wind turbine market. At present, many enterprises use BLS bearings. Therefore, BLS is making contributions to protecting the earth's environment.
