The world's solar cell production on both sides will surpass 60% this year.
Deep groove Ball Bearing is the most representative structure in rolling bearing, which is widely used. In addition to radial load, this kind of bearing can also be loaded with bidirectional axial load. The friction torque is small, and it is most suitable for adjusting rotation, low noise and low vibration. Bearings are widely used in automobile, electrical, instrumentation, construction machinery, agricultural machinery and various professional machinery. This kind of bearing has open and closed deformation structure.
Deep groove ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls. The standard Conrad-type bearing has a deep-groove construction capable of handling radial and axial loads from either direction in versatile designs that permit relatively high-speed operation.

China is the world's largest producer of photovoltaic industry. The biennial photovoltaic conference is the highest event in China's photovoltaic industry. Here, 304 photovoltaic companies from both sides of the Taiwan Straits and overseas gathered in Nanjing to discuss the development prospects of the photovoltaic industry and understand the latest achievements in the technological progress of China's photovoltaic industry.
The photovoltaic industry is an emerging industry that is highly valued by all countries in the world. The world's photovoltaic industry is represented by solar cell production, with an average annual growth rate of 48.5% in the last 10 years. The average annual growth rate in the past five years has reached 55.2%. In the world photovoltaic industry, the photovoltaic industry of the mainland and Taiwan both play an important role in the international market.
Since 2007, after the mainland and Taiwan became the world's first and fourth largest producers of solar cells, the exchanges and cooperation between the two sides in the photovoltaic industry have become increasingly close.
According to Professor Wei Qidong, Secretary General of Jiangsu Photovoltaic Industry Association, Taiwan is an internationally renowned optoelectronic industry base. It has maintained a high-speed growth in optoelectronic technology research and advanced manufacturing for many years, and has obvious competitive advantages in the international market, while the mainland, especially Jiangsu, Has a good foundation for the development of the optoelectronic industry. In recent years, the two sides have continued to expand cooperation in this industry, and have firmly occupied the position of the world's photovoltaic industry, and its share is increasing year by year.
Shi Dinghua, chairman of the China Renewable Energy Society, said that among the top 15 battery manufacturers in the world, the two companies on the two sides accounted for 9 companies, including 6 in the mainland and 3 in Taiwan. It is expected that in 2015, the world's photovoltaic cell production will be Up to 130GWp.
