The bearing industry is the basic industry of the manufacturing industry and is also an important industry supporting the country's major equipment and precision equipment manufacturing industries. Its development has played an important role in the development of China's manufacturing industry.
In recent years, China's bearing manufacturing industry has a strong momentum of development, which will bring about positive effects on the smoothness of the bearing steel market. Demand for a number of high-end bearings has increased significantly, such as aerospace bearings, high-speed precision bearings for machine tool spindles, precision angular contact ball bearings for ball screw support, high-speed spindle bearings, turntable bearings, wind power bearings, joint bearings for shield machines, etc. . Large demand has created the development of a large number of enterprises.
According to statistics, there are currently more than 1,400 bearing enterprises in China, employing more than 300,000 people. In 2011, China's bearing manufacturing industry achieved a total industrial output value of 193.211 billion yuan, a year-on-year increase of 27.59%, sales revenue of 1.9107 billion yuan, an increase of 30.30%, a total profit of 12.523 billion yuan, an increase of 26.54%.
Although the overall trend is positive, with the evolution of global economy and integration today, the bearing industry has also encountered significant challenges, including acceleration of product life cycles, highly customized product requirements, and global market competition. Intensified and other issues. To solve these problems, the bearing industry needs to start from many aspects.
First, improve product technology content, work efficiency, reliability and accuracy
From the perspective of the current product structure of China's bearing industry, the production capacity of ordinary bearings with relatively low technological content is relatively sufficient; bearings with high precision, high technology content and high added value have special characteristics and can meet the special working conditions of self-lubricating bearings. No matter if it is a variety or quantity, there is ample room for development. From the perspective of product quality and technology, China still needs a lot of high-end bearings every year.
Raising the R&D, design, and manufacturing capabilities of plain bearing manufacturers is the only way to achieve high-tech, high-reliability, high-efficiency, and high-precision bearings. With the support of national policies, with the rapid development of China's equipment manufacturing industry, it is expected that the enterprises of the sliding bearing industry will focus on improving the accuracy, performance, longevity, and reliability of bearing products. China's plain bearing manufacturers have continuously increased their R&D and design levels and manufacturing levels by increasing R&D efforts and introducing advanced manufacturing equipment from abroad, which is in line with the inevitable trend of future industry development.
Second, to achieve high-flexibility and large-scale production, the pursuit of better quality
The manufacture and production of the modern bearing industry, especially the production and production of small and medium-sized bearings, are basically characterized by a small number of large quantities of products. Therefore, the production line of such large-bearing bearings has a high degree of automation, as well as high production efficiency and equipment utilization. However, only one or several very similar products corresponding to the design of the production line can be processed. With today's high-speed replacement of products, continuous refinement of customer demand and even customization, the market has increasingly demanded more varieties of small batch bearing products. In the face of this situation, this "rigid" or low-flexibility production line is either powerless or the cost of adjustment is too high. Therefore, to increase the flexibility of the production line and maintain the same low cost as mass production—that is, high-flexibility and large-scale production is an important challenge for intelligent manufacturing of bearings in the future.
Moreover, with the development of the bearing industry in China, the bearing products produced in China have gradually entered the procurement scope of users at home and abroad who pay great attention to product quality. However, these customers not only value the technical content of the product, but also value the quality of the product. The company pursues better product quality, strictly controls product production, and helps product
Third, according to the specialization of the market segmentation further reflected
Sliding bearings, especially self-lubricating bearings, have different types and specifications due to their different uses. Different types of sliding bearings require different levels of heat treatment, precision of car machining, surface treatment methods, automation of production devices, and manufacturing processes. Therefore, existing sliding bearing companies basically focus on a specific area or market segment. After hundreds of years of development, the international bearing industry has formed a stable and specialized division of labor. The international bearing giants organize specialized production in their respective market segments. In the future, domestic manufacturers of sliding bearings will further clarify product positioning, take the path of specialization and division of labor, and do a good job of subdividing the market to achieve economies of scale.
