Analysis of Japanese Bearing Competitiveness in China Bearings

How to make the domestic bearing industry continue to develop in the fierce market competition, improve product quality, open up new potential markets, increase the share of the bearing products in the international market and competitiveness, is the current domestic bearing industry urgently solve the problem. Japan is a leading manufacturer of precision bearings, and has taken the lead in the world in terms of product development, design and manufacturing, technology level, product quality, and production equipment.

In order to further understand the current situation of Japan's bearing production and market, recently, at the invitation of the Mayor of Kobe, Japan, the delegation of the Chinese bearing industry organized by the Planning and Marketing Department of China Machinery Industry Federation and the China Machinery Industry Branch of the International Trade Promotion Committee recently A 10-day visit to Japan was a complete success. The delegation was headed by Song Xiaogang, deputy secretary-general of the China Machinery Industry Federation, consultant of the planning and marketing department of the China Machinery Industry Federation, and Sun Zhenbin, senior expert of China's bearing industry. The delegation was composed of the China Bearing Industry Association and Harbin Bearing Group. Luoyang Bearing Group Co., Ltd., Chongqing Changjiang Bearing Industrial Co., Ltd., Zhejiang Xinchang Xi Miike Bearing Co., Ltd., Fujian Nanan Bearing Co., Ltd. and other 13 units consisted of 24 members. After examining the Japanese bearing manufacturing companies, the delegation members felt deeply about the advanced production technologies used by Japanese companies. After returning home, some of the techniques and management methods were soon applied to their own companies. Through the communication and exchanges between the leaders of the Chinese and Japanese bearing companies, this has further promoted the trade between China and Japan.

During the visit, the delegation members considered that the production and operation of Japanese bearing companies had the following characteristics:

First, advanced technology and equipment, product manufacturing levels, work efficiency and high. Into the production workshop of a Japanese company, rows of equipment were neatly stacked, the motor roared, and there were very few workers in the workshop. For large batches of standard bearings, it is basically responsible for 1 to 2 production lines per person. A series of processing procedures such as part loading, loading, processing, inspection, cleaning, assembly, oil coating, packaging, etc., are completely completed by high-precision and high-efficiency automated equipment, and advanced processing and inspection technologies, such as adaptive grinding technology, online Measurement technology, fault self-diagnosis technology, etc. have been widely used, thereby reducing the product quality unfavorable caused by human factors, and the work efficiency is very high. Another example is the Japanese bearing company's production of ball bearing grinding processing automatic lines of the existing two modes, one for the grinding process automatic line process equipment, an automatic line inside and outside the ring a total of 18 sets of equipment, one person to look at two grinding super automatic line. 6200 grinding super line beat 4.8 seconds / piece, the workshop has a total of 8 automatic lines, managed by 4 people, monthly production of 1 million sets. Another automatic grinding line consists of 27 devices with only 2 persons in charge and 400,000 sets per month.

The second is to create a professional production pattern and maintain quality brands. Japan's bearing company production is mainly heat treatment process, grinding process, assembly process. All rough machining processes and parts are outsourced. Each component has 2 to 3 companies and the company supplies it. This kind of specialized production pattern has created good benefits for enterprises, with labor productivity of up to 3 million yuan each. Whether it is NSK or NTN, the reason why it is world-famous is undoubtedly due to its excellent quality. For the ultra-high precision requirements of customers, they consistently report the highest reliability. They advocate the standardization of production at global production bases. Nearly half of NSK's ball bearings are produced at overseas factories, and they can also maintain the same high quality as Japan's home production. Because of this, NSK and NTN products with bearings as their leader are always in sync with the most advanced technologies of the era.

The third is to adjust the industrial structure to meet the market demand. Japan's bearing companies in the structural adjustment, change the market strategy, change blindly attack to advance and retreat. Its strategic features are: implementation of closure, stop, and transfer, optimization and combination. Expand the market for superior products and shrink the market for weak products. General-purpose bearings are adjusted in large quantities and at low cost; multi-species and small-batch bearings are adjusted to the unit direction. Japanese companies generally attach importance to product development, and based on the premise that the economy has no borders, they are based on global development strategies. The company's unique products are continuously introduced, and new products that meet the requirements of the host can be provided before the host invests according to the needs of users. This has won the trust of consumers around the world.

Fourth, Japanese bearing companies focus on the development of manufacturing technologies and processes. Among the manufacturers visited by the delegation, companies are highly automated production and online automatic detection. However, on the production line, not all equipment is the most advanced, and some are equipment of the 1960s or 1970s, but they can be combined with production lines and can guarantee product quality, thanks to the general emphasis on production by Japanese companies. Technology development. Most of the companies visited by the delegation are manufacturing plants, but the technical development departments have strong development capabilities. While paying attention to the development of new products, they also focus on the development and innovation of production technologies and processes to ensure the quality of products.

After visiting and inspecting, the delegation members believed that the following production technologies could be used by domestic enterprises for reference.

Bearing grinding and bearing assembly automatic line technology.

Bearing automatic line online automatic detection technology.

Precision steel ball manufacturing process and testing technology.

Heat treatment production line material automatic arrangement technology.

Ball bearing double-end grinding machine inner and outer ring wear technology.

CBN abrasive use technology.

The members of the delegation learned from this visit that although China has become the world’s largest producer of bearing products after Japan, the United States, and Germany in terms of total bearing production volume and production system, its product development capabilities, product quality levels, and production From the point of view of manufacturing scale, there is still a big gap between our country and the strong country of bearing production. Chinese enterprises should strengthen technical cooperation with Japanese companies, especially small and medium-sized enterprises, and combine the advantages of Japanese companies' technology, capital, and management with the advantages of China's market, manpower, and resources to achieve mutual benefits and common development.

In order to further promote the better development of China's bearing industry, the delegation members, in conjunction with the “Tenth Five-Year Plan” development plan for China's machinery industry, put forward the following suggestions:

1. The current bearing industry is not strong, small enterprises do not specialize, the loose state of the relationship between the enterprises less, into a big company, small, special, large and small between companies, with a reasonable combination of small Baoda situation.

2. Bearing enterprise internal organizational structure from the "olive type" to "dumbbell type" change.

3. The capital structure of bearing enterprises has shifted from a state of heavy emphasis on state-owned capital to a coordinated development of public, private and foreign-owned enterprises.

4. The bearing product structure is made up of low-grade bearing products, and ordinary bearing products are often transformed into high-quality bearing products. The physical quality of the bearing must be close to or reach the level of international bearing brand-name products; from the emphasis on the final product, emphasis on tangible products, to the emphasis on intermediate products at the same time. , value service value added.

5. Accelerating the technological progress of enterprises and improving the technological innovation capabilities of enterprises, the valve trading network will transform the existing backward cluster-type production methods into a linear production method.

6. Promote the construction of specialized production systems to increase labor productivity and reduce production costs. Pump valve trading network companies to master the main body, separation assistance; adhere to the fine processing, including rough machining, finished products, parts and components outside the bearing production professional development direction.

7. Accelerate the pace of internationalization and strengthen economic and technological cooperation with foreign countries. Encourage qualified bearing companies to build factories abroad.
