Wind power is rapidly gaining popularity in countries around the world as a clean energy source that does not produce carbon dioxide, which can contribute to the greenhouse effect.

Large wind turbines (windmills) are giant machines, and many of the 2MW-class wind turbines now under construction have windmill blades about 40 meters long and rotating shafts 60 to 100 meters high, with a total weight of no less than 200 tons. Therefore, the bearings used in windmills are also necessarily large, with inner diameters ranging from 100 mm to 700 mm, and some models require bearings with inner diameters of nearly 2 meters. There are only six manufacturers, including NSK, that can stably supply these large bearings to the market. The wind turbine industry is now an industry that is developing on a global scale, and therefore, in addition to bearing manufacturing, marketing activities and technical services at major outlets around the world are important conditions.

Wind turbine bearings are a special kind of bearings that are used in harsh environments, high maintenance costs and require high life expectancy.
