Bearing products has more than ten thousand kinds of more than 10

Bearing analyses current situation of the development of bearing in China is important in modern mechanical equipment indispensable basic parts. Although the rise of more than hundred years of history, however, because of the relationship between national economy and people's livelihood, all countries are spare no effort to develop the domestic bearing industry, lease superb modern science and technology, bearing production has more than ten thousand species, more than 10 varieties excellent quality, superior performance, the development of mechanical industry and other industry all over the world, made outstanding contributions to the progress of human society. International bearing main production countries and regions of China, Germany, Sweden, Japan, ten years ago, has formed the eight dominant pattern in a multinational company, its market share of 80. More than 00%, has more obvious technical advantage. Bearing industry in our country has formed a larger scale, currently accounts for about 10 of the total amount of bearing industry markets around the world. 180, 00% in 2011, the industry bearing production. 0 billion sets, 1420 sales. 0 billion yuan, the third largest in the world. But compared with the world bearing industrial powers, China bearing industry still exists a certain gap, main show is high precision, high technology content and high value-added products proportion is low, product stability, further improve, etc. In recent years, with the vigorous development of the economy, China's bearing industry supporting ability to greatly enhance the independent innovation ability and national economy, China's bearing industry has been able to produce more than 70000 specifications of various types of bearings, basic can satisfy the demands of national economy and national defense construction of form a complete set. Bearing belongs to a mechanical components, bearing industry is a technology-intensive, capital-intensive and labor-intensive compatible industry. Because of the low barriers to entry, and lack of exit mechanism, a large number of small business enterprise make China bearing industry concentration degree is low, and pour directly to the China bearing market fierce competition; At the same time, the world's eight major bearing companies have factories in China and domestic sales channels, makes China bearing market competition more intense, the new round of world economic structure adjustment to the bearing industry in our country provides the new development opportunity, industry scale of the size of the company will use its own advantages, management advantages, brand advantage, quality advantage, into the bearing manufacture high-end and core technology, to further consolidate and expand its market share, industry concentration will be improved. Strive to occupy the initiative position in the international division of labor and a bigger market share. Bearing industry technology level of Chinese bearing industry advantage developed 16 key enterprises in the field of 13 of the 106 kinds of major technical equipment in the field of supporting bearing of 528, reached the level of similar foreign products. But big and bearing industry in China is not strong, the bearing manufacturing process and equipment technology development is slow, the car processing CNC automation level is low, many technical difficult problem has not been able to make a breakthrough, technological bearing steel research and development of new steel grade and the improvement of steel quality, lubrication, cooling, cleaning and grinding tools and other related technology research and development, is not to meet the requirements of bearing product level and quality and affect the accuracy, performance, life and reliability of the bearing. At present our country bearing manufacturing enterprise through the introduction of advanced process equipment, as well as through its own research and development, bearing industry overall technical level had the very big enhancement, part of the production enterprises, including the issuer process equipment has reached the international advanced level. The present salt quenching heat treatment production line of the world's advanced level and only a handful of firms, including the issuer can grasp.
