The bearing industry is the basic industry of the manufacturing industry and an important industry supporting the national major equipment and precision equipment manufacturing industry. 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 bring positive effects to the steady improvement of the bearing steel market. The demand for a number of high-end bearings has grown significantly, such as aerospace bearings, high-speed precision bearings for machine tool spindles, precision angular contact ball bearings for ball screw supports, high-speed motorized spindle bearings, turntable bearings, wind power bearings, shield machine joint bearings, 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 enterprises in my country, employing more than 300,000 people. In 2011, the total industrial output value of my country’s bearing manufacturing industry was 193.211 billion yuan, a year-on-year increase of 27.59%.

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 reduction of product life cycle, the high customization of product demand and the competition in different global markets. exacerbated problems. 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 with special characteristics and can meet special working conditions. , whether it is variety or quantity, there is a large 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 R&D, 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, 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 as a key investment direction. my country’s sliding bearing manufacturers have continuously improved the level of research and development, design and manufacturing 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 highly 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 have the characteristics of small varieties and large quantities. Therefore, the production line of such high-volume bearings is highly automated, and the production efficiency and equipment utilization 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 upgrading of today’s products, the continuous refinement and even customization of customer needs, the market demand for multi-variety and small-batch bearing products is increasing. In the face of such a situation, such “rigid” or low-flexible production lines are either incapable or too costly to adjust. 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 intelligent bearing manufacturing in the future.

Moreover, with the development of my country’s bearing industry, the bearing products produced in my country have gradually entered the procurement scope of some 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 the quality of the product. Enterprises pursue better product quality and strictly control product production, which is conducive to product quality.

3. Further reflect the specialized division of labor according to market segments

Sliding bearings, especially self-lubricating bearings, exist in many varieties and specifications due to their different uses. Different types of sliding bearings have different requirements for heat treatment level, machining accuracy, surface treatment method, automation degree of production equipment and manufacturing process, so the existing sliding bearing enterprises basically focus on a specific field or market segment. After hundreds of years of development, the international bearing industry has formed a stable and specialized 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 specialized division of labor, strengthen and fine-tune the market, and achieve economies of scale.
