Precision cross tapered roller bearings move towards clustering of characteristic industries

At present, the market environment of China's cross-tapered roller bearings is changing, and the policy environment for industrial development is also changing. In the past, the government used to use stimulus to promote development, but now it is seeking a new impetus for economic development by comprehensively deepening reforms. For the transformation and upgrading of enterprises, in the past they were more accustomed to using administrative means to promote, but now they rely more on market forces.

Similarly, in terms of product technology and industrial scale, China's cross-tapered roller bearing industry has made great breakthroughs. During the development of the crossed roller bearing industry, the Chinese market has always insisted on innovation and development, and strengthened technical exchanges with developed countries, which greatly enhanced the strength of the crossed tapered roller bearing industry in China and enhanced the product market. Competitiveness. Many precision bearing brands have emerged influencing at home and abroad.

Although the international competitiveness of the products has improved in recent years, most of them are concentrated in the low-to-medium range. Such products have low added value, and some high-precision crossed tapered roller bearings still need to rely on imports. Take the spindle bearing of precision machine tool as an example. The spindle bearing is used as the basic supporting part of the machine tool bearing. Its performance directly affects the speed, rotation accuracy, rigidity, anti-vibration cutting performance, noise, temperature rise and thermal deformation of the machine tool, and then affects Precision of machined parts, surface quality, etc. For the spindle support of high-speed and high-precision machine tools such as CNC machine tools and machining centers, super precision bearings of P4 and above grades need to be selected. With the rapid development of numerical control technology, "composite, high speed, intelligent, precise, and environmental protection" has become the main trend of the technology development of the machine tool industry today.

Among them, high-speed processing can effectively improve the processing efficiency of the machine tool and shorten the processing cycle of the workpiece. This requires the machine tool spindle and its related components to adapt to the needs of high-speed processing. At present, about 150,000 sets of p4 and above ultra-precision angular contact ball bearings are required by the machine tool industry, and about half of them come from famous foreign bearing companies such as FAGNSKSKF. In addition to psychological factors and brand effects, the technical performance and reliability of bearings are the main reasons for machine tool customers to choose imported cross tapered roller bearings. While foreign precision cross tapered roller bearing products have excellent performance and high reliability, there are disadvantages such as high price, long delivery time, and delayed after-sales service.

In the future development, the industry and related companies must make up their minds, devote themselves to research and development, pay close attention to the research of new technologies and new technologies, and gradually form a multi-field, comprehensive scientific research and development pattern with division of labor, collaboration, and multi-disciplinary research and development. The property rights of the precision crossed tapered roller bearings, through the absorption of advanced manufacturing experience, advanced technology and high-level talents, to improve the design and manufacturing of precision crossed roller bearings.
