When China's high-speed rail leads the world with a total mileage of 45,000 kilometers, it still needs to spend billions of dollars annually on importing bearings; when the annual domestic production of bearings exceeds 30 billion sets, the high-end market is monopolized by the eight international giants with a 75% share. The question of "whether domestic precision bearings can surpass imports" has always lingered in the journey of manufacturing industry upgrading. In Wuxi, a hotspot for manufacturing, Zhongfu Power (Wuxi) Co., Ltd. has given a clear response after ten years of deep cultivation: domestic bearings are breaking the monopoly with technological breakthroughs, achieving a leap from following to running alongside in the precision manufacturing race.
The breakthrough of domestically produced bearings has long been constrained by dual bottlenecks in materials and technology. Bearing steel, known as the "king of steel," has a purity that directly determines the product's lifespan. Foreign companies, leveraging their core technologies, process the basic raw materials and sell them back at a tenfold premium. Meanwhile, the lifespan of domestically produced bearings was once only one-third of that of imported products. In terms of processing accuracy, imported bearings can meet P4 standards, with a roundness error not exceeding 0.5 micrometers, equivalent to the surface undulations of an apple-sized Earth not exceeding the width of a human hair. Meanwhile, mainstream domestic products have long remained at the P5-P6 level.
The breakthrough for Zhongfu Dynamics begins with precisely tackling its core weaknesses. Since its establishment in 2014, the company has embedded the pursuit of excellence into its R&D genes. Relying on the advantages of the Yangtze River Delta industrial cluster, it closely follows the wave of technological breakthroughs in rare earth bearing steel. The low-oxygen rare earth steel developed by the Institute of Metal Research, Chinese Academy of Sciences, has improved fatigue performance by more than 40 times. Zhongfu Dynamics quickly transformed this material achievement into product competitiveness. Its "JOJI" brand bearings, through the introduction of high-end processing equipment and independent process optimization, achieve micron-level precision control, achieving high-speed, quiet, and durable operation in the fields of motors and precision machine tools, directly benchmarking against the international top level.
In the dual test of performance and scenarios, the product strength of Zhongfu Dynamics has been fully verified. In the high-temperature and heavy-load environment of the metallurgical industry, its bearings utilize an upgraded sealing structure to block dust and moisture, extending equipment life with low friction performance. In the "rotating head" of wind turbines, slewing bearings support the continuous operation of the equipment. In robotics and automated production lines, high-precision bearings ensure precise operation requirements. These breakthroughs in application scenarios echo the requirements for tackling "bottleneck" technologies outlined in the "14th Five-Year Development Plan for the High-end Bearing Industry," and also confirm the significant progress made in the reliability of domestic bearings. It should be noted that the reliability of imported bearings was once 2 percentage points higher than that of domestic ones, but this gap is being continuously narrowed by companies such as Zhongfu Dynamics.
Even more significantly, Zhongfu Power has achieved a leap from "domestic manufacturing" to "global recognition". The company has obtained dual certification of ISO9001 and the European Union's CE mark, and its products are exported to Europe, America, Russia, Southeast Asia, and other regions, competing head-on with imported brands in the international market. This competitiveness not only stems from product quality but also from the service innovation of "one-stop procurement". In addition to its own brand, it integrates domestic and foreign resources to provide customers with a full range of solutions such as bearings and lubricants. This flexibility is an advantage that many international giants find difficult to match.
Currently, China's bearing industry is experiencing a dual benefit from both policy and market: the central government has established a special fund worth billions of yuan, providing a 15% R&D subsidy for technological breakthroughs in precision bearings above P4 level. By 2025, the market size of high-end bearings is expected to exceed 80 billion yuan. Amidst this wave, the practice of Zhongfu Dynamics provides a clear answer: the path to surpassing domestic precision bearings does not rely on utopian "one-step solutions", but rather on solid progress based on technological innovation, deep exploration of application scenarios, and connecting global resources.
From the steady increase in the localization rate of high-speed rail bearings to the bulk export of wind turbine main shaft bearings, Chinese bearings are rewriting the global industrial landscape. Wuxi Zhongfu Power has proven with its small bearings that when "Made in China" combines precision, resilience, and innovation, the goal of surpassing imports is not just empty talk, but a reality that is happening now.
