China's bearing industry to the present, already have considerable production scale and high technology, quality standards.
Bearing a certain size has grown to more than 1,500 enterprises,cast bronze number of employees growing to nearly 80 million people, bronze bushing bearing annual production from 13.8 million in 1949 increased to more than 20 million units, bearing varieties of the cumulative increase from 100 to more than 7000 specifications up to 28000. Past 10 years,dry bushing bearing well-known foreign companies (such as SKF, FAG, NSK, NBM, KOYO, TIMKEN, TORRINGTON, etc.) have set up factories in China's investment on the technology of raising the level of bearing design,plain bearing production technology and production management specification, production equipment level of modernization,sleeve bushing product quality and performance improvement has played a significant role in promoting.
On the other hand,DU bushing bearing manufacturers in China are also facing bearing well-known companies from foreign competition and challenges,bushing the results would accelerate the industrial structure of China's bearing industry and the pace of adjustment of product structure, described as the opportunities and challenges, production and development with the. How to seize opportunities,brass bushing improve the viability of enterprises in existence at the same time to obtain the sustained and rapid development is placed in front of China's bearing industry can not be avoided, Mould guide plate can not be avoided.
At present,plasic bushing China's bearing output of more than 20 million units, the output value has exceeded 200 billion yuan, the export volume of more than 770 million units, exports about 700 million U.S. dollars, ranked No. 4 in the world, to meet the domestic need more than 70% of product variety, meet the required number of 90%, export volume also increased a higher proportion.
In our country into the ranks of the world's largest producer of bearings, we should also see lower bearing industry, scattered, the problem of poor, ordinary micro, small, medium and small deep groove ball bearings are still a large number of low-level repetitive production, resulting in serious oversupply , due to intense market competition, price war intensified. If this situation continues long is bound to affect the entire bearing industry transformation and technological progress, of bearing products in China's international reputation, has seriously hampered the healthy development of China's bearing industry.
Strict quality requirements, high added value and still requires a lot of imported bearings. For example, car bearing, high-speed, quasi-high speed railway bearings, bearings for all kinds of imported equipment maintenance, some high-precision, high value-added and special working conditions in the use of larger bearings supply gap, the production of bearing products in our performance and price ratio, high precision, low noise, long life and high reliability, and foreign famous enterprises there is a big gap.
