In terms of material research and development
New steel research and development: Researchers are committed to improving the formula and production process of bearing steel, enhancing the purity, uniformity, and performance of steel. For example, by precisely controlling the alloy element content in steel and adopting advanced refining techniques to reduce impurities and defects, the strength, toughness, and wear resistance of bearing steel are significantly improved, which can meet the requirements of high-end bearings in high-speed, heavy-duty, high-precision and other working conditions.
Application of special materials: In addition to traditional bearing steel, some special materials such as ceramics and carbon fiber reinforced composite materials have also been increasingly used in the field of bearings. Ceramic bearings have the advantages of high hardness, high temperature resistance, corrosion resistance, and light weight, and are suitable for high-speed, high-precision, and high load working environments, such as aerospace, high-speed machine tools, and other fields. Carbon fiber reinforced composite materials have good strength and stiffness, and can also reduce the weight of bearings, which has unique advantages in some weight sensitive equipment.
Process upgrade aspect
Precision machining technology: With the widespread application of advanced machining equipment such as CNC machine tools and precision grinders, the machining accuracy of domestically produced bearings has been greatly improved. By adopting high-precision processing techniques such as precision grinding and ultra precision grinding, the dimensional accuracy of bearings can be controlled at the micrometer or even nanometer level, and the surface roughness can also reach an extremely low level, thereby improving the operational accuracy of bearings, reducing friction losses and noise.
Heat treatment and surface treatment technology: Advanced heat treatment processes, such as vacuum quenching, induction quenching, etc., can achieve good microstructure and performance of bearing parts, improve their hardness, strength, and wear resistance. At the same time, the application of surface treatment technologies such as nitriding, hard chromium plating, spraying, etc. can not only improve the hardness and corrosion resistance of the bearing surface, but also improve its lubrication performance, reduce the friction coefficient, and extend the service life of the bearing.
Digital and intelligent production: use industrial Internet, big data, artificial intelligence and other technologies to realize digital monitoring and intelligent management of bearing production process. By establishing a Production Information Management System (MES), real-time production data can be collected to optimize and schedule the production process, improve production efficiency, and reduce costs. In addition, the application of intelligent robots in bearing production is becoming increasingly widespread, achieving automation of processes such as loading, unloading, and assembly, reducing the impact of human factors on product quality.
In terms of industrial chain collaboration
Industry university research cooperation: Strengthen cooperation between universities, research institutions, and enterprises to jointly carry out research and innovation in bearing technology. Universities and research institutions have strong research capabilities and talent resources, which can provide theoretical support and technical guidance for enterprises; Enterprises have rich production experience and market demand information, and can quickly transform scientific research achievements into actual products. Through industry university research cooperation, the process of technological innovation has been accelerated, promoting the upgrading of the domestic bearing industry.
Collaboration between upstream and downstream enterprises: The close collaboration between upstream and downstream enterprises in the bearing industry chain has achieved coordinated development from raw material supply, component processing to bearing assembly, sales, and other links. For example, steel companies collaborate with bearing companies to jointly develop high-performance bearing steel materials; Component suppliers collaborate with bearing manufacturers to improve the quality and accuracy of components, ensuring the overall performance of bearings. This collaborative development model helps to enhance the overall competitiveness of the industrial chain and achieve optimized allocation of resources.
Market and policy aspects
Market demand driven: With the rapid development of China's high-end equipment manufacturing industry, the demand for high-performance bearings in fields such as new energy vehicles, wind power, robotics, aerospace, etc. continues to increase, providing a broad market space for domestic bearing enterprises. At the same time, the demand for imported bearings in the domestic market is constantly increasing, prompting domestic bearing enterprises to accelerate technological innovation, improve product quality, and meet the needs of the high-end domestic market.
Policy support and guidance: The country has introduced a series of policies to support the development of the bearing industry, such as establishing industry funds, special subsidies, implementing the "unveiling and leading" mechanism, etc., encouraging enterprises to increase research and development investment and break through key core technologies. These policies provide financial support and policy guarantees for domestic bearing enterprises, which helps to promote the rapid development of the industry.
