Market analysis precision machine tool bearings

     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.
