Future Bearing Enterprises Will Further Increase The Development Of Materials To Meet The Needs Of Production And Management
Aug 12, 2018

Bearing is one of the most important parts in modern mechanical equipment. Its main function is to support the rotating shaft or other moving body, guide the rotation or movement and bear the load from the shaft or parts on the shaft. Its performance, accuracy and reliability play a decisive role in the normal operation of the user.

Bearing products are widely used. According to the main engine supporting types can be divided into automobile bearings, electrical bearings, machine bearings, household appliances bearings, railway bearings, metallurgy mining machinery bearings, engineering machinery bearings, petrochemical machinery bearings, wind power bearings, agricultural machinery bearings and so on. Among them, automobile industry is a large application market of bearing products in China, accounting for about 30% in terms of the required quantity. Demand for other bearings, such as household appliances, electricians and machine tools, is also growing steadily.

China bearing industry sales revenue

According to the data statistics of "analysis report on production and marketing demand forecast and transformation and upgrading of bearing manufacturing industry" released by forward-looking industry research institute, the main business revenue of China's bearing industry from January to October 2015 was 222.549 billion yuan, and the main business revenue was 274.1 billion yuan in 2014, up 222.5 billion yuan from 51.6 billion yuan in 2005, with a compound growth rate of 18%. The bearing growth rate is expected to slow in the future, but it will not be lower than the GDP growth rate because the bearing is a necessary part of all kinds of machinery.

Market competition in bearing industry

More than 70% share of the world bearing market is Shared by ten multinational bearing groups. The United States, which accounts for 23% of the global market, the European Union, which accounts for 21%, and Japan, which accounts for 19%, are basically dominated by five companies, including NSK of Japan, SKF of Sweden, FAG of Germany, and Timken of the United States. At the same time, the high-end market of the world bearing industry is monopolized by these enterprises, while the middle and low market is mainly concentrated in China. At present, the concentration degree of China's bearing industry is not high. Although the degree of automation, product stability and accuracy have been greatly improved, there is still a certain gap compared with some well-known overseas enterprises, and there is even a gap in the research and development of some core technologies.

The proportion of the world's major bearing markets

In China's bearing industry, automobile and motorcycle bearings are the industry's largest users. At present, China has basically achieved localization in the wheel bearings of heavy trucks. However, only a few enterprises, such as wanxiang qianchao, have made breakthroughs in the wheel bearings of medium and high-end cars. Import substitution has just begun.

The development of ABS is a typical example of the development of automobile related products. In the future, with the increasing requirements of safety and environmental protection, the miniature bearing will produce many new applications. The import of the bearing market aimed at hybrids and electric vehicles will create new types of vehicle-related products. In this development, the field of micro-bearing will be expanded and its precision will be improved continuously. With the continuous development of China's automobile industry, the development space for domestic enterprises is huge.

Domestic manufacturers need to improve their r&d and innovation capabilities

Because our country most bearing enterprises in the innovation system of research and development funding, construction operation, personnel training and other aspects behind the international leading enterprises, the accuracy of bearing noise, life, such as closing a factors are not fully meet the requirements of high-end machinery, therefore, in the aerospace, high-speed railway passenger cars, luxury cars, computers, air conditioner, high pressure bearing machine, high speed machine tools and other equipment, need a lot of bearing important rely on imports. With the technical investment and equipment improvement of bearing enterprises, bearing independent innovation capacity will be greatly enhanced, and innovative products are expected to replace imported products and traditional products.

It is an inevitable trend to improve product technical content, work efficiency, reliability and accuracy

It is the only way to improve the r&d, design and manufacturing capacity of sliding bearing manufacturers to achieve high technical content, high reliability, high efficiency and high accuracy. With the rapid development of China's equipment manufacturing industry under the support of national policies, it is expected that enterprises in the sliding bearing industry will focus on the improvement of precision, performance, life and reliability of bearing products in the future. By increasing research and development efforts and introducing foreign advanced manufacturing equipment, Chinese manufacturers of sliding bearings have been continuously improving their research and development design and manufacturing level, which is in line with the inevitable trend of future industrial development.

The research and development ability of lubricating materials plays an important role in designing and producing sliding bearings

The surface material and lubrication property of sliding bearing determine the wear resistance and pressure resistance. In order to meet customer demands, different types of sliding bearings have different requirements on surface materials. Therefore, the r&d ability of sliding bearing enterprises for sliding materials largely determines the speed of business expansion. In the future, sliding bearing enterprises will further enhance the development of sliding materials to meet the needs of production and operation.
