Wind Power Industry Introduction


SINOMACH Sealing focuses on the sealing research in wind power equipment, rapidly industrializes wind power seals through independent research and development and technology accumulation, and has made several technological innovations in the field of wind power seals, and has developed a range of high-performance, high-reliability sealing products and customized sealing solutions that are widely used in a variety of wind power equipment, providing strong support for the development of the wind power industry.
SINOMACH Sealing products have been applied to more than 80,000 wind turbines to ensure their normal operation, and the product applications cover 31 provincial administrative regions in China, except the Tibet Autonomous Region, Hong Kong, Macao and Taiwan. For Goldwind Science & Technology, Envision Energy, Mingyang Wind Power, Guodian United Power, Dongfang Turbine and other domestic wind turbine enterprises supporting high-performance, high-stability sealing products, and with the whole machine exported to Africa, Asia, America, Europe and Australia, more than a dozen countries and regions such as the United States, Panama, India, Thailand, France, Australia, the longest operating time of more than 12 years.
SINOMACH Sealing’s wind power equipment sealing solutions are widely used in the main shaft bearings, gear boxes, electric generators and cabin covers, among other key parts of sealing. According to the special needs of key components, we have developed various types of sealing products, such as dust seal, guide series, rotary seal, etc. to meet the sealing needs of different working conditions.
Wind Power Sealing Solution
Main Bearing Seat Sealing Solution
Wind power main bearing seat sealing plays a vital role in wind power equipment. Its main purpose is to isolate the external environment from the internal environment of the bearing, to prevent external impurities from entering the bearing seat, to ensure the cleanliness of the bearing seat and the cleaning and lubricating effects of the lubricating oil, and at the same time to prevent the leakage of the lubricating oil.

Multi-lip Seal Series


Gearbox Sealing Solutions
Gearbox sealing is an important measure to ensure the proper operation and to extend the service life of the gearbox. By choosing the appropriate sealing methods, materials and technologies, the intrusion of external impurities and the loss of lubricating oil can be minimized and the performance and reliability of the gearbox can be improved.
Oil Seal Series


Gearbox Integrated Thin Oil Lubrication Unit Sealing Solution
To adapt to the trend towards integrated wind power gearboxes, a sealed system structure adapted to thin oil lubrication was developed. It is assembled by a number of axial assembly components, so that the sealing system has multiple sealing functions and lubrication medium guiding functions, can meet the current wind power cost reduction (lightweight), sealing function is perfect, easy maintenance, less maintenance (maintenance-free) and other requirements.


● Long Life
● Light Weight
● Reduce Costs
● Oil Liquid Circulation
● Easily Maintained
Other Sealing Solutions
Custom yaw brake seals, pitch bearing seals, gearbox static seals, reduction box seals and other solutions are available to meet the sealing requirements in different operating conditions.

As a professional seal technology solution provider in the wind power industry, our company will continue to be committed to technological innovation and product research and development in the field of wind power, and will participate in technical exchanges and cooperation in the wind power industry to contribute more to the development of the wind power industry. At the same time, the company will also actively fulfill its social responsibilities, promote the universal use and application of clean energy, and contribute to the cause of environmental protection.
