Deep groove ball bearing is the most common type of rolling bearings, simple structure, easy to use, in the production of the most common use, the most widely used. At present, our country has formed a relatively complete system of production and technical system for deep groove ball bearings, and has become the fourth largest country in the world bearing production after Japan, the United States and Germany, and has made great achievements.
The researchers pointed out: deep groove ball bearings are widely used, many manufacturers in China, with Chinas bearing products continuously improve the quality of the emergence of a number of high-quality goods bearing generation enterprises, the quality of their products have with international brands, exports will continue to expand the scale, the deep groove ball bearing will maintain an annual growth rate of about 20%.
Deep groove ball bearings are mainly subjected to radial loads and radial loads and axial loads simultaneously. The contact angle is zero when it is only subjected to radial load. When the deep groove ball bearing has larger radial clearance, it has the performance of angular contact bearing, and can bear larger axial load. The friction coefficient of deep groove ball bearing is very small, and the limit speed is high. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of retaining structures. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is divided into two kinds of seal and open structure. The open type means that the bearing does not have sealing structure, and the sealed deep groove ball is divided into dustproof seal and oil proof seal.
Compared with the industrial power of deep groove ball bearing industry in the world, there is still a big gap in China. The main performance is the low proportion of high precision, high technology and high value-added products, poor product stability, low reliability and short life. Reflected in the market, that is, Chinas demand for high-quality bearings also rely on imports to meet. It is because of the lack of varieties, performance and other aspects of the deep groove ball bearings in China, therefore, most of the export products are low grade products, and the competitiveness is not strong in the world, which restricts the long-term development of the industry.
