Aligning ball bearings

The 17th century, Galileo "Fixed ball", or "caged ball" ball bearings done earliest descriptions. However, for a long time in the subsequent years, the bearing is installed on the machine has not been achieved. The first patent on the ball channel Carmarthen Philip Vaughan acquired in 1794.
Aligning ball backing bearings
In 1883, Friedrich Fischer proposed the use of suitable production machine grinding the same size, roundness accurate idea of ​​the ball. This laid the bearing industry to create an independent foundation. "Fischers Automatische Gußstahlkugelfabrik" or "Fischer Aktien-Gesellschaft" later became the first monogram trademark in 29 July 1905 registered.
1962, FAG this trademark has been modified and still in use, and in 1979 became an integral part of the company.
In 1895, Henry Timken design a first tapered roller bearings, three years later obtained a patent and the establishment of Timken Company.
In 1907, SKF bearing factory Sven temperature Qwest designed the first modern self-aligning ball bearings.

Development of the industry
Bearings are an important foundation for all types of machinery and equipment parts, and its accuracy, performance, life and reliability of the host precision, performance, longevity and reliability play a decisive role. Mechanical products, bearings are precision products, not only in mathematics, physics and many other disciplines integrated support for the theory, but also materials science, heat treatment, precision machining and measuring technology, digital technology and efficient numerical methods and powerful computer technology and many other disciplines to serve, so the bearing is also a representative of national scientific and technological strength of the product.
According to "China Bearing Manufacturing Industry Market Research and Analysis Report Preview" analysis, in 2008 after the outbreak of the international financial crisis, the national response to the financial crisis, has taken to increase infrastructure investment and stimulate economic development in the proactive fiscal policy. Benefit from the development of related industries, the rapid expansion of the bearing sales, profit levels have been improved significantly accelerated development of the industry. According to the National Bureau of Statistics, in 2011 the scale of China Bearing Manufacturing Industry (annual sales income of 20 million yuan or more) companies a total of 1,416 enterprises, the annual industrial output value of 193.211 billion yuan, an increase of 27.59%; sales revenue of 191.097 billion yuan, an increase of 30.30%; total profit of 12.523 billion yuan, an increase of 26.54% over last year.
In recent years, the world-renowned enterprises have entered the Chinese bearing market and establish production bases, such as the Swedish SKF Group, Schaeffler Group USA Timken Company, Japan's NSK Corporation, NTN Corporation. These companies are not only operates globally and is the global manufacturing, by virtue of their brands, equipment, technology, capital and production scale advantages, and domestic bearing enterprises engaged in a fierce competition. Domestic enterprises are mainly engaged in the production of general bearing, special bearings and high-end producers less technology is not mature. Therefore, domestic enterprises are to compete with foreign advanced bearing brands, and even beyond, technology and other aspects also need to go through a long period of development.
"Twelve Five" period, the state will continue to show the effect of macroeconomic policies, domestic economic growth remains strong, the international market will recover slowly, and gradually increase the momentum of economic recovery. Development of national economy will boost infrastructure investment, thereby promoting metallurgy, electric power, construction machinery, building materials, energy and other industries, while the state has adopted ten industrial revitalization plan, the automotive, aerospace, machine tools, wind power and other industries provide policy support for the development of these industries on the bearing demand will be gradually expanded. In addition, the state of the importance of the equipment manufacturing industry and the bearing localization trend is increasingly evident that China bearing market will usher in a broader space for development. Meanwhile, with the development of China's bearing hosting industry, bushings product mix will change, its high-end products in the product increased the proportion of unit sales will increase as well, it is expected that by 2015, China's bearing production is expected to more than 28 billion sets, the main business income is expected to reach 210 billion yuan, becoming the world's largest bearing manufacturing and sales base.
With the Precision bearing manufacturing industry competition intensified, large bearing manufacturing enterprises merger and acquisition and capital operation is becoming more frequent, excellent domestic bearing manufacturers more and more attention on the industry market research, especially on the industrial development environment and product buyers in-depth study. Because of this, a large number of excellent domestic bearing manufacturers brand has risen rapidly, becoming a leader in bearing manufacturing industry!
