The development trend of my country's bearing industry

As a precision mechanical basic part, rolling bearings are a highly versatile and highly standardized rotating support element. Its impact on the performance and service life of the host is very critical and important. Rolling bearings have various structures, and their applications cover all walks of life from military to civilian. Whether it is a space shuttle rocket launch tower or an underground drilling rickshaw, the role of bearings can be seen.
In the production process of various types of rolling bearings, assembly is the last important step. Due to the diversity of bearing structures, the assembly methods of bearings are also diverse, but the basic process is to assemble qualified bearing parts into finished products to meet the expected requirements and ensure the performance of the bearings. The assembly process of bearings starts from parts cleaning, size sorting, fitting inspection, and ends with oiling and packaging. The process is not simple and requires high quality of operators. The level of assembly represents the level of bearing production and processing of an enterprise, and also represents the level of bearing quality.
With the development of the equipment manufacturing industry, the level of bearing assembly is also developing rapidly. The degree of mechanization and automation of assembly has gradually increased, and some assembly lines have achieved unmanned operation. The improvement in the level of grinding and processing of bearing parts has brought convenience to assembly. Some parts that could not be assembled interchangeably before can now be assembled directly without sorting. Key bearings that did not meet the original precision of finished products can now be assembled.
In the past two decades, my country's bearing industry has developed rapidly, and a large number of high-quality bearings have been exported, attracting worldwide attention. The country already has a relatively complete scientific research, academic and processing system composed of school scientific research units that train various talents and various bearing manufacturing enterprises. It has achieved remarkable results in developing varieties, pursuing individuality, improving quality, increasing output, improving processes, saving materials and reducing consumption. . By designing and manufacturing automatic assembly lines or automatically operated machines by ourselves, and by introducing advanced foreign fully automatic bearing assembly lines and technologies, my country's bearing assembly technology level continues to reach new heights.
However, we must see that with the development of bearing varieties and output, more updated assembly technologies and equipment will inevitably be required to adapt. Continuously improving the level of assembly automation, gradually realizing full automation of large-volume products, unremittingly improving my country's bearing assembly technology level, and improving bearing assembly quality and assembly efficiency are still a long-term and arduous task before us.
At present, domestic bearing manufacturing enterprises have multiple systems coexisting, and the equipment levels of bearing assembly are different. The level of assembly personnel is also different, and the requirements for bearing assembly are also different. But even so, the analysis of the basic principles and basic issues of bearing assembly is still the same.
