     Statistics show that in 2002 China's high speed bearing industry, the annual output of 2.8 billion units of various types of bearings, which, P5 grade precision bearings 62,364,000 units, P4 Extra Precision 729 000 units. Annual sales of products bearing the used machine tool manufacturing industry has 33 million sets.

     Analysis of market distribution in 2002 domestic precision machine tool bearings, precision machine tools for various types of P5 and above-bearing approximately 1.5 million units, which is used by about half of the machine tool spindle bearings and ball screws. P4 and above-grade super-precision bearings and paired bearings (mainly referring to the spindle bearings and ball screw bearings) about 15 million units.

     According to the machine tool industry, "15" planning objectives, to 2005, the annual output of 20 metal processing machines to 22 million units, including CNC machine tools to 3 to 3.5 million units (2003 CNC machine tools production and sales have exceeded 300 million units ), accounting for 15% of total production, domestic machine tool market share of 60 to 65%. As in recent years, the rapid development of China's machine tool industry, to 2005, the annual production of metal processing machines certainly more than the machine tool industry, "fifteen" planning objectives, in addition, with the development of modern machine tools to high-speed, high efficiency, composite direction, precision machine tools with precision miniature ball bearings capita will increase dramatically. Taking into account the huge transformation tools and repair market, the analysis and calculation predicts that in 2005 total of metalworking machine tools supporting the more than 50 million sets of bearings, P5 and above-grade precision bearings around 300 million units, of which approximately 1.5 million units for machine tools and a ball screw spindle. These bearings are larger amount of deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, angular contact thrust ball bearings and tapered roller bearings.

     Ball bearing spindle bearings and precision control as machine parts, P4 level and above super-precision bearings and bearing paired proportions and will greatly increase in the proportion of 20% by 2002 up to 2005 of 40% to 50% so, a total of about 700,000 units.

     In addition to psychological factors and branding, technical performance and reliability of the bearings are machine customers to choose the main bearings. If the technical indicators and reliability levels of domestic super precision bearings and bearings can be quite the next two years the market has great potential.

     To this end, the major domestic machine tool bearings supporting enterprises, such as: , Bearing Group Corporation, has begun to accelerate the pace of technological innovation, increase capital in processing conditions, testing methods, matching technology and reliability research investment, the main models of the small group of trial products and some types of mass-produced products have reached the international advanced level, import substitution is only a matter of time and scale of the problem.

     Although foreign precision machine tool self aligning roller bearings  excellent performance, high reliability, but there are expensive, long delivery times, service lag and other issues. In addition, the accuracy rating of P2-level super-precision bearings, are cutting-edge technology, these products are also classified as foreign to the country of export restrictions column. Domestic bearing production enterprises should seize the opportunity of rapid development of China's machine tool market, scale, accuracy, improve the stability of product quality, to meet the machine tool industry for bearing accuracy, high speed, low noise, high reliability, strict requirements At the same time, improve their own R & D capability, processing capacity, distribution networks and other comprehensive competitiveness.

   

China's bearing machine tool industry status and development trend

Machine tool industry as an important part of the machinery and equipment industry, plays an important role in the development of the entire national economy. Overall, from the industry, China's machine tool industry is currently in the best since 1992 development period, showing a shortage of good market situation. Especially since 1999 has entered a new growth for a long time, China's ferris wheel bearing tool industry output growth year after year, constantly adjusting product structure, increasing product quality. The following table since 1999, the output value of machine tool industry, metal cutting machine tool production, the growth in production of CNC metal cutting machine tools:
From a global perspective, China's machine tool consumption in 2002 compared with 2001 growth of 20.0%, accounting for the proportion of the world's total machine tool consumption rose from 13.6 percent to 19.2 percent, jumped from fourth in the world to first.
Meanwhile, in the case of the domestic machine tool industry production and management continue to maintain good momentum this year, China's machine tool imports also continued to grow, until the end of September, according to customs statistics, China's vertical mill bearing tool imports reached 2.96 billion yuan, increase of 35% over last year. Moreover, some well-known international companies have wholly-owned, joint ventures, etc. entering the country, the use of cheap labor costs and a variety of favorable conditions to seize the Chinese market. This fully shows that the machine is now modern manufacturing industry in international competition has gradually into the Chinese hinterland. China will continue to maintain its position as the world's first importer and consumer countries.

     Although in recent years, China's machine tool industry has made great progress, but in the current domestic and international machine tool market is extremely competitive situation, China's machine tool industry is even less competitive, mainly in the country is also a big consumer machine not machine power, but the machine has a large amount of low-level, product mix is still lagging behind, product innovation ability, machine reliability to be improved and so on.

     The level of the world's machine tool manufacturing concentrated expression in the development of CNC machine tools, production capacity, CNC machine tools has become a mainstream manufacturing equipment, a country has the number of CNC machine tools, the level has become the measure of a country's comprehensive strength, an important sign . To achieve our transformation from a big country for machine tool production powerhouse goal, we must accelerate the pace of adjustment, increase new product development efforts. For this reason, the machine tool industry, "15" plan proposes to focus on the development of CNC machine tools, thus boosting the industry to improve the overall level. Total goals formulated as follows: the 2005 National wind power bearing production to reach 25,000 to 30,000 units, the output value reached 65 to 70 billion, CNC machine tool market share reached 50% (by value). From the current situation, expected 2003 production target ahead of schedule.

How to buy Agricultural Bearings

Bearing is rotating shaft of various mechanical or moving parts support, widely used in farm vehicles, tractors, diesel engines, electric motors, threshers and other agricultural machinery. Choose Common bearing code, but bearing code more complicated, if agricultural hand grasp identification bearing code of law, the purchase is easy.
Bearings are some of the commonly used standard model, codenamed "0" tolerance class "G" (ordinary level), the general agricultural bearings of the first paragraph can not write, so its more than seven-digit code representing the basic code.
To illustrate the meaning of bearing code: Example 7002136 (135 series diesel engine shaft main bearings), the basic code from right to left to identify. "36" within a two-digit representation of light, which is calculated as 36 × 5 = 180 mm; "1" represents the diameter of the series special light; "2" indicates the type of cylindrical roller bearings; "00" indicates the form of the outer bearing structure without ribs; "7" represents the width of the narrow series. If the machine hand to buy other standard models bearing seven-digit code can and so on.
Optional multi-reference bearing diameter bearings, tower crane bearing diameter in the basic code using the right end of the first, second digit indicates. Sub-standard and non-standard bearing bore diameter, the difference is not an integer or a non-standard inner diameter of the whole multiple of 5.
To facilitate machine hand purchase.
To illustrate:
① bearing diameter in 9 mm below the right end of the first digit is represented by the actual size. For example, the bearing 18, an inner diameter of 8 mm.
② bearing diameter of 10 - 17 mm is represented by a set number. Such as bearings 100, 201, 302, 403, an inner diameter of the right end of the two-digit code is respectively 00, 01, 02, 03, respectively, an inner diameter of 10, 12, 15, 17 mm fixed numbers.
③ bearing diameter in 20--480 mm (22, 28, except 32), in addition to the inner diameter of 5 resulting numbers.
④ bearing diameter of more than 500 mm (22, 28, 32), expressed as a fraction, the denominator represents the inner diameter, the numerator represents the size of the series, the type and structure of the deck crane bearing

. Example No. 30031/560 bearings, an inner diameter of 560 mm, the other and so on.
