As we join the WTO gradually from the international competition to the fore, China's bearing industry has been stable and rapid development.

According to the national bureau of statistics annals, in 2004 the bearing industry, the state-owned and state holding enterprise and annual sales of 5 million yuan of above of the non-public owned enterprise has reached 927 in 2003, the industry bearing production is 4.1 billion sets, bearing sales income is 39.2 billion yuan, China bearing sales have leapt fourth world, as the world bearing production country. Especially tiny, small deep groove ball bearing capacity has become the largest country in the world.

Deep groove ball bearing as NSK bearings, SKF bearing, FAG INA bearing, bearings, NTN bearing, KOYO bearing, TIMKEN bearing, NACHI bearing import bearing of a seed, because of its wide application, long service life, is widely used in the modern equipment manufacturing industry in, make the equipment the machining precision, and quality is obtained for the ascension, it can be said that deep groove ball bearing in future equipment device will receive large application, and its market prospect will be more vast.
 
Deep groove ball bearing general by a contractor a group of maintains a, a group of just a group of ball and keep frame structure, deep groove ball bearing type code for 6. Is the production of the most commonly, the most widely used kind of bearing. Deep groove ball bearing structure is simple, easy to use, is the production batch maximum, withstand the axial load. When bearing radial clearance increase, with angular contact ball bearing function, can bear the larger axial load
