The world's machine tool industry faces the most difficult challenges that continue to be thrown by the world economic recession. At the same time, the economic recession has a profound impact on the capital product market. In addition to a weak financial environment, machine tool manufacturers are also dragged by the processing component market, such as manufacturing, automotive and real estate. Therefore, with the recession drawing to a close, the recovery of economic fundamentals will help the recovery of the machine tool industry. Due to the wide range of applications of machine tools, including aerospace, automotive, processing, wind power, mining and oil exploration industries, this will facilitate the rapid recovery of the machine tool industry, Luo Baihui, executive director of the International Association of Mold and Hardware & Plastics Industry Suppliers. According to the analysis, although Europe and the Asia-Pacific region still account for most of the global machine tool market, the recovery of the machine tool market will be mainly driven by emerging markets such as China and India. At present, the demand for machine tools in North America shows a strong growth signal, and its output and demand have increased rapidly in recent months.
The interactive development of the Asian-European machine tool market In recent years, the demand for important equipment manufacturing industries such as defense, aviation, high-speed rail, automobiles, and molds has grown substantially. This has led to a significant increase in the machine tool industry. The average annual production of CNC machine tools in the past five years has been compounded. The growth rate was 37.39%, the average annual compound growth was 29.94% in the past 10 years, and the compound growth was 22.10% in the past 15 years. Driven by the revitalization of the equipment manufacturing industry and the transfer of international industries, the growth rate of China’s investment in equipment and tool purchases will continue to be around 20% in the next 5 to 10 years. The demand for the machine tool industry will continue to grow at a high rate. According to Luo Baihui, executive secretary general of International Die & Metal & Plastics Industry Suppliers Association, driven by the demand, the output of CNC machine tools in China has maintained rapid growth. With the deepening of economic restructuring, the growth of listed companies in CNC machine tools and CNC system equipment has grown rapidly. It is expected to continue. In 2010, CNC machine tools consumed more than 6 billion U.S. dollars and the number of machines exceeded 100,000 units, indicating that CNC machine tools have become the mainstream of machine tool consumption. China's future market for CNC machine tools is huge.
In 2010, China's CNC metal-cutting machine tools grew significantly, with output increasing by 66.71% year-on-year, an increase of 67.17 percentage points over the previous year. In the past 10 years, the average annual compound growth rate of China's CNC metal-cutting machine tool production was 31.93%. The growth data for 2010 means that the development of CNC metal cutting machine tools has entered a new phase.
On the export side, except for a small number of high-end and heavy-duty machine tools, they may continue to make breakthroughs and enter the international market; middle and low-end CNC machine tools, high-quality ordinary machine tools suitable for user needs, and metal cutting tools and abrasive tools, forging and stamping tools, machine tool accessories And so on, will still be favored by the international market and users.
On the import side, the proportion of imports of large heavy-duty machine tools and expensive machine tools may continue to decline. The import of key components required for domestic companies to develop high-end machine tools and heavy-duty machine tools will increase. According to Luo Baihui, executive director general of the International Die & Metals and Plastics Industry Suppliers Association, the import and export of China's machine tool industry will continue to grow in 2011, the structure of import and export products will improve, and the European machine tool industry will recover.
According to the preliminary statistics of the Italian Machine Tool, Robotics and Automation System Manufacturers Association, Italy's total output value of this industry in 2010 was approximately 4.23 billion Euros, an increase of 3.3% over the same period of 2009. In 2010, Italian manufacturers' sales in the country amounted to 1.625 billion euros, an increase of 3.8% from the same period of last year. During the same period, the export volume was 2.605 billion euros, an increase of only 3.1% year-on-year. Statistics from January to September 2010 show that the total value of Italian machine tools exported to China exceeds 270 million euros, surpassing Germany to become the largest export market for the Italian machine tool industry, and the US market ranks third. It is noteworthy that Italian machine tools have fallen in sales from traditional export markets such as Germany, the United States and France, but India (83.8% year-on-year), Russia (16.4%), Iran (312.5%) and Brazil Emerging markets such as (47.7%) have seen significant growth.
In Asia, India’s gross domestic product has grown by 5%-9%, making it the second fastest growing economy in the world. The rapid economic growth in India mainly comes from the drive of agriculture, services, manufacturing, trade and construction. In order to restore industrial growth and maintain this momentum, the Indian government has taken a series of positive responses. In the coming years, the Indian machine tool industry will strive to achieve an annual growth rate of 35%, and export will account for more than 30% of the output value, and will continue to maintain its low-cost advantage. According to forecasts, the output value of the Indian machine tool industry will increase from Rs. 14.25 billion in the fiscal year 2008-2009 to Rs. 31 billion in the 2010-2011 fiscal year. Due to the economic recovery and the prosperity of the automotive and parts industries, the volume of orders has increased significantly. In two years, the growth rate of the Indian machine tool output reached 117.5%. By 2020, the size of the industry will reach Rs. 230 billion. In order to develop Indian machine tool technology, increase production, reduce dependence on imports, provide continuous manufacturing competitiveness and enhance national security, the Indian Machine Tool Industry Association has made the localization rate of Indian machine tools increased to 50% by 2020. Increased to 67%, the industry's compound annual growth rate (CAGR) for the next 10 years will reach 25%. For this reason, the Indian machine tool industry needs to invest 40 billion rupees in the next 10 years in order to strengthen technology research and development to enhance the competitiveness of the industry.
At present, the Indian machine tool industry has 450 machine tool manufacturing companies, of which about 33% (about 150 machine tool manufacturing companies) are within the scope of government-owned companies. In addition, India's ten major machine tool builders account for almost 70% of the value of Indian machine tools. The Hindustan Machine Tool Co., Ltd. owned by the Indian government alone accounts for 32% of the output value of the Indian machine tool industry. About 75% of India's machine tool producers are eager to obtain the certification of Indian machine tool products by the International Organization for Standardization (ISO). When the products of large machine tool manufacturers meet the needs of India's heavy industry, the products of small-scale machine tool companies meet the needs of other companies.
The Indian machine tool industry is basically similar to industrial developed countries. It started late but has a high starting point. The factory buildings are not large but they are all steel structures. Most of them are built with three-dimensional magazines; the products are all CNC machine tools with mid-range and above, and they do not meet the needs of India for manufacturing five-axis and large CNC machine tools. There are not many employees, but the proportion of technical personnel and sales personnel is high, and English and computers are generally mastered. Computer applications are very popular. The per capita annual sales income of these companies is about 80,000 to 90,000 U.S. dollars, about 600,000 yuan. The company attaches great importance to export and overseas market development, to adapt to India's national conditions, attach importance to the implementation of turnkey projects to users, and pay attention to user services. The enterprise attaches importance to the construction of corporate culture and humanistic management, and pays attention to improving the cohesion of the enterprise.
According to the analysis of the European Machine Tool Industry Cooperation Council (CECIMO), since the end of 2009, orders accepted by European machine tool manufacturers have been increasing. In the first half of 2010, its growth rate was almost 60% of the same period in 2009. Affected by the strong growth of imports and exports in China, India and other Asian markets, all European industrial products have seen an increase. In the first half of 2010, EU-27 exports to China increased by approximately 40% year-on-year. Recent statistics show that while international orders have grown at a double-digit rate, growth has slowed. This shows that after the economic recession, the euro zone fell into a sovereign debt crisis, dragging the pace of economic recovery. Although the recovery is still continuing, the current industry output is still lower than the pre-crisis level.
Throughout the product export line, exports of advanced technology products ranked first. In the first half of 2010, about 60% of EU27 countries’ machinery and vehicle products were exported to China. In the machinery industry, especially the machine tool industry, the product value mainly comes from R&D and design. European industrial strategies must ensure high investment in high value-added products. According to Luo Baihui, executive director of the International Mould, Hardware and Plastic Industry Suppliers Association, the European machine tool industry is traditionally export-oriented, but European customers are still the core support of our industry. Because manufacturing has always been an important part of the European economy and the main driver of economic recovery.
President Obama proposed the slogan "The United States must return to the manufacturing industry." The Japanese government also took measures to control the merger and acquisition of the machine tool industry. In order to completely emerge from the crisis and maintain a strong European industrial base and maintain the leading position of European manufacturing industry and the development of enterprises, EU policy makers expressed their desire to support manufacturers' initiatives to revitalize R&D capabilities and open up new solutions.
Recently, the European Union has promulgated a series of initiatives. One of them is Key Enabling Technologies (KET). It will play an important role in promoting future products and services. Advanced Manufacturing System, one of the six KETs, can produce products efficiently, environmentally, and sustainably across departments.
According to FilipGeerts, Director-General of the European Machine Tool Industry Cooperation Council (CECIMO), CECIMO's leading position in the world machine tool industry association is mainly due to the cutting technology and perfect solutions that they provide. Although their competitors have adopted similar strategies, they still stay ahead. According to FilipGeerts' forecast, the production of the European machine tool industry in 2011 will be significantly better than in 2010, and this balanced and sustainable upward trend will continue in the coming years. However, it will not return to the 2008 level in the near future.
As the world’s largest machine tool consumer in the world, China’s self-sufficiency rate in the high-end CNC cutting machine industry is seriously low, and there is a large gap between the world’s advanced countries in design and R&D, materials technology, and parts and components. While benefiting from the country’s industrial policy, the huge demand of the downstream industry has won valuable development opportunities for the CNC cutting machine tool industry in China, continuously increasing the consumption capacity and the infrastructure construction that the regional revitalization plan has spawned. It is determined that China's auto market and construction machinery market will continue to maintain a good growth for a long period of time, which will determine the good prospects for the growth of China's CNC machine tool market. Luo Baihui, executive secretary of the International Mould, Hardware and Plastic Industry Suppliers Association pointed out that China is focusing on the development of emerging industries such as clean energy, electronics, medical equipment and aerospace, and has great demand for high-efficiency, high-precision, and high-automation manufacturing equipment. As the main machine tool supplier in the Chinese market, CECIMO has established a good relationship with China. Our good reputation is based on innovation and the provision of high-quality manufacturing solutions for overseas industries. As a sincere partner of European customers, we have provided European customers with the required products, and have successfully provided customers with production solutions worldwide, achieving a win-win situation for both parties. At the same time, more and more European manufacturers have decided to set up factories in China, which will create more added value and provide more employment opportunities for China. Luo Baihui said that he welcomes no interference from regulations, administration and procedures. Free international trade rules must strive to break the implementation of policies that are detrimental to the interests of suppliers and users. Of course, we have no doubt to ensure respect for intellectual property rights, because any economy must achieve sustainable development, and the protection of intellectual property rights is crucial.
According to statistics, since 2010, the growth rate of production and sales of the machine tool industry has been more than 40%. The compound growth rate of the machine tool industry in the next five years is 25% to 30%, and high-end CNC cutting machine tools will become the main force for growth. Luo Baihui explained that “the growth momentum comes from the continuous upgrading of existing products and gaining international market share. On the other hand, it comes from technology research and development and product innovation. It enters key product areas supported by the country and forms a new growth point.â€

Nylon Cage Self-aligning Ball Bearing
Nylon cage Self-aligning ball bearings are one type of Self-aligning Ball Bearing. Include two rows of balls, the ATN nylon cage, the inner ring, and the outer ring with a common concave sphered raceway. Self-aligning ball bearing have a sphere raceway in the outer ring and a double raceway in the inner ring. This feature give the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing. Nylon cage self-aligning ball bearings are therefore particularly suitable for applications where misalignment can arise from errors in mounting or from shaft deflection. Double row self-aligning ball bearings are mainly used to carry radial loads and light axial loads, but cann't carry pure axial loads.
Feature:
Mainly bear radial load, and can bear smaller axial load. Axis (shell) axial displacement limit in the clearance limits, the heart performance is automatically adjusted, normal work allows the inner and outer relatively small tilt conditions, suitable for bearing hole can not strictly ensure the concentricity. Self-aligning ball bearings are consequently self-aligning and insensitive to shaft deflections and angular misalignment of the shaft relative to the housing, It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected.
Main Application
Owning to its specific structure, the self aligning ball bearing can be used in some relative field and some general lines.For example, Self-aligning ball bearing applies to carry heavy load and impact load. Mine machine, port hoisting machine, port transfer equipment.
