As a "time-honored" force in China's bearing industry, Harbin Bearing Group Co., Ltd. (hereinafter referred to as Jianlong Harbin Bearing) has made another success in the field of aerospace - recently successfully completed 5 categories and more than 7,000 sets of aerospace supporting tasks, providing strong support for the independence of key components of aerospace equipment with hard-core technical strength. This achievement is not only a concentrated display of 75 years of technological accumulation, but also highlights the mission and responsibility of national industry in the field of high-end equipment.

Deeply cultivating aerospace supporting technology to overcome extreme working conditions

In the journey of independence of key components of aerospace equipment, the Jianlong Harbin Bearing technical team has always been at the forefront. Faced with complex and harsh working conditions in the aerospace field - from the extreme temperature difference in the space environment, overload under high-speed operation, to the extreme requirements of precision instruments for bearing stability, the R&D team relies on the full-chain innovation system of the national enterprise technology center to carry out in-depth research in core links such as material selection, structural design, and process optimization.

In response to the reliability problems faced by spacecraft in the ultra-long service cycle, the team has gone through years of research and development. Through the application of new materials and surface modification technology, the fatigue resistance of bearings in extreme environments has been effectively improved; to ensure the stable operation of precision instruments and actuators, the R&D personnel have optimized the bearing raceway design for multiple rounds and successfully achieved the low vibration and high precision operation requirements. With these technological breakthroughs, HRB products fully cover the core components of various systems in the aerospace field and become the reliable "Chinese core" of aerospace equipment.

The spillover effect of technological innovation is benefiting the field of civilian high-end equipment. In the supporting mission of the world's largest cargo drone "White Whale W5000", Jianlong Harbin Bearing transformed and applied aerospace-grade precision manufacturing technology, and related products successfully passed the rigorous static machine combination test, marking the successful practice of "civilianization of aerospace technology".

Deeply cultivating aerospace supporting technology to overcome extreme working conditions

Since starting as a national key project during the "First Five-Year Plan" period, Harbin Bearing's indissoluble bond with China's aerospace industry has continued for more than 70 years. From manned spaceflight to Chang'e lunar exploration, from launch vehicles to domestic aircraft, HRB bearings have always been silently guarding every take-off of a major country's heavy equipment with stable and reliable performance. Whenever a national project puts forward a high-difficulty supporting demand, the company can always respond quickly, with solid technical accumulation and rigorous craftsmanship, and deliver excellent results under extreme technical requirements.

After joining Jianlong Group in 2020, Jianlong Harbin Bearing's innovative potential in the field of aerospace has been further released. The intelligent production line of Jiangbei Bearing Industrial Park realizes digital control of the entire process from design to delivery, with an automation rate of 95% for key processes and a 50% increase in product consistency. While improving production efficiency, the company has always adhered to the original intention of "every bearing is related to aerospace safety" - the quality control of aerospace products maintains strict standards to ensure zero defects before leaving the factory.

Innovation-driven development consolidates the high ground of aerospace technology

"Making every bearing for the aerospace industry" is a mission engraved in the genes of Harbin Bearing people. In the "bottleneck" fields such as aircraft engine bearings and deep-sea equipment bearings, the company is working with the industry's top scientific research forces to carry out collaborative research and development, focusing on breaking through core technical bottlenecks such as high-temperature lubrication and extreme environment sealing. In the past five years, Jianlong Harbin Bearing has continued to increase its investment in the field of aerospace research and development, and has built a leading metrology and inspection laboratory in the domestic bearing industry, providing strong test guarantees for the development of high-end bearings.

Standing at a new starting point, Jianlong Harbin Bearing is continuing to consolidate its technological advantages in the field of aerospace bearings, deepen cooperation with aerospace research institutions, increase investment in intelligent manufacturing, and help my country's aerospace industry to reach new heights with better products. At the same time, it will extend its aerospace-grade technological advantages to the field of civilian high-end equipment, and use solid technical accumulation to build a solid foundation for the "Chinese bearings" of a major country.

Seventy-five years of original aspirations, seventy-five years of craftsmanship. Facing the future, Jianlong Harbin Bearing will continue to use innovation as an engine, climb to the top in the technical breakthroughs of aerospace bearings, and contribute more "Harbin Bearing Power" to my country's transition from an aerospace power to a strong country with more outstanding products and deeper accumulation, so that "Chinese bearings" will shine brighter on the journey of the stars and the sea.
