Bearing industry is introduced, the present situation, development

　　　　Bearings. Its main function is to support the axis of rotation, or other movement of the body, rotating or moving during movement and the transfer of the load on the shaft or shaft parts, can be divided into two categories, the rolling bearing and sliding bearing. Introduction Of NTN Bearing is using a wide range of mechanical industry, demanding a matching parts and components. Due to the use of a wide range, determine the bearing varieties of diversity and complexity. Because of the strict, determines the importance of bearing quality and performance. Rolling bearings are widely used in industry, agriculture, transportation, national defense, aerospace, household appliances, office machinery and high-tech fields. According to the products use purposes, can be roughly divided into ball bearings rolling bearing, the centripetal bearing, thrust bearing, ball bearing, roller bearing, etc.
　　　　After Japan, the United States and Germany bearing industry of our country in the world. 4. But compared with the bearing industrial world powers, also there is a big gap between bearing industry of our country, mainly characterized by high precision, high technology content and high value-added products proportion is low, product stability, low reliability and short life, etc.  
　　　　Total bearing enterprises in our country occupies the first place in the world, but most of the enterprise scale is not big, the competition ability is not strong, weak ability to resist risks. Traditional five big domestic bearing enterprises accounts for about 20% of the country's total production of bearings, Germany's big three bearing production accounted for 96% of total national output, the four companies in the United States (56%), Japan's five major companies share up to 99.2%.
　　　　
Bearing export growth is lower than import growth, high-end bearing products in our country is still dependent on imports. According to statistics, in 2005 China's export products bearing in micro, small and small and medium-sized deep groove ball bearings and small, medium and small tapered roller bearings, needle roller bearings and other products, and high precision, high technology content and high added value bearing ratio is low. Export market mainly concentrated in the United States, Japan and the European Union and other countries and regions.
