As a clean energy that does not produce carbon dioxide and can run greenhouse effect, wind power is rapidly expanding around the world.
Large wind turbines (windmills) are enormous machines, within now 2MW wind power facilities are under construction. The windmill blades are about 40 meters height, the rotation axis are 60 to 100 meters height, the total weight is no less than 200 tons. After all, the use of windmill bearings are also very large, the diameter range range from 100 mm to 700 mm, some models need nearly 2 meters diameter bearings. Only NSK and other 6 suppliers worldwide can provide the market supply of such large bearings manufacturers. Wind turbine industry is now a global developing industry. Therefore, how to promote the bearing manufacturing and maintenance service is another important factor besides manufacture.
Wind turbine bearings require high reliability because this bearing is designed to ensure a windmill to operate 20 years without substitute maintenance. Especially the parts are not easy to replace during operating. (When the bearing is used for tens of meters from the ground). Therefore, the bearing manufacturers require a high accuracy of computer analysis and exquisite craftsmanship in materials and heat treatment, sometimes also need to master the large-scale bearing evaluation.
For all of the above requirements, TURNUP has the highest strength in the bearing industry. In the meantime, we also continue to promote these strengths throughout the development so that we meet the expectations of the market.
