The bearing industry is the basic industry of the manufacturing industry, and it is also an important industry supporting the national major equipment and precision equipment manufacturing industries. Its development has played an important role in the development of my country's manufacturing industry.
In recent years, the development momentum of my country's bearing manufacturing industry has been strong, which will have a positive effect on the stability and improvement of the bearing steel market. The 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 supports, high-speed electric spindle bearings, turntable bearings, wind power bearings, joint bearings for shield machines, etc. . The large demand has created the development of a large number of enterprises.
According to statistics, there are currently more than 1,400 bearing companies in my country, with more than 300,000 employees. In 2011, my country'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 191.097 billion yuan, a year-on-year increase of 30.30%, and a total profit of 12.523 billion yuan, a year-on-year increase of 26.54%.
Although the overall situation is improving, with the evolution of global economy and integration, the bearing industry has also encountered great challenges, including the accelerated shortening of product life cycle, high customization of product demand and competition in different global markets. exacerbation of issues. To solve these problems, the bearing industry needs to start from many aspects.
1. Improve product technical content, work efficiency, reliability and precision.
Judging from the current product structure of my country's bearing industry, the production capacity of ordinary bearings with low technical content is relatively sufficient; while bearings with high precision, high technical content, and high added value are self-lubricating bearings that are special and can meet special working conditions. , whether it is variety or quantity, there is a lot of room for development. From the perspective of product quality and technical level, my country still needs to import a large number of high-end bearings every year.
Improving the research and development, design and manufacturing capabilities of sliding bearing manufacturers is the only way to achieve high technology content, high reliability, high efficiency and high precision of sliding bearings. With the support of national policies, and with the rapid development of my country's equipment manufacturing industry, it is expected that enterprises in the sliding bearing industry will focus on improving the accuracy, performance, life and reliability of bearing products in the future. my country's sliding bearing manufacturers have continuously improved their R&D, design and manufacturing levels by increasing research and development efforts and introducing foreign advanced manufacturing equipment, which is in line with the inevitable trend of future industry development.
2. Realize high flexible mass production and pursue better quality
The manufacturing and production of the modern bearing industry, especially the manufacturing and production of small and medium-sized bearings, basically has the characteristics of small varieties and large quantities of products. Therefore, the production line of such high-volume bearings has a high degree of automation, and the production efficiency and equipment utilization rate are also high. But only one or several very similar products corresponding to the design of the production line can be processed. With the high-speed replacement of products today and the continuous refinement and even customization of customer needs, the market demand for multi-variety and small-batch bearing products is increasing. Faced with such a situation, this "rigid" or low-flexibility production line is either powerless, or the adjustment cost is too high. Therefore, improving the flexibility of the production line and maintaining the same low cost as mass production—that is, high-flexibility mass production is an important challenge for future intelligent manufacturing of bearings.
Moreover, with the development of my country's bearing industry, the bearing products produced in my country have gradually entered the purchasing scope of some users who pay great attention to product quality at home and abroad. However, these customers not only value the technical content of the product, but also the quality of the product. Enterprises pursue better product quality and strictly control product production, which is conducive to product quality
3. According to the specialization of market segments, it is further reflected
Sliding bearings, especially self-lubricating bearings, have many varieties and specifications due to their different uses. Different types of sliding bearings have different requirements on heat treatment level, machining accuracy, surface treatment method, automation degree of production equipment and manufacturing process, so the existing sliding bearing companies basically focus on a certain specialized field or market segment. After hundreds of years of development, the international bearing industry has formed a stable professional division of labor. International bearing giants organize specialized production in their respective market segments. In the future, domestic sliding bearing manufacturers will further clarify product positioning, take the road of specialization and division of labor, strengthen and refine the market, and achieve scale effect.
