As a time-honored force in China’s bearing industry, Harbin Bearing Group Co., Ltd. (hereinafter referred to as Jianlong Harbin Bearing) has once again achieved success in the aerospace field – it has recently successfully completed more than 7,000 sets of aerospace supporting tasks in five categories, providing strong support for the independent development of key components of aerospace equipment with its hard-core technical strength. This achievement is not only a concentrated display of 75 years of technological accumulation, but also demonstrates the mission and responsibility of the national industry in the field of high-end equipment.
Deeply cultivate aerospace supporting technologies to overcome extreme working conditions
In the journey of independent development of key components of aerospace equipment, the technical team of Jianlong Harbin Bearing has always been at the forefront. Facing the 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 during their extremely long service life, the team has spent years of research and development, and through the application of new materials and surface modification technology, has effectively improved the fatigue resistance of bearings in extreme environments; to ensure the stable operation of precision instruments and actuators, R&D personnel have optimized the bearing raceway design for multiple rounds and successfully achieved the low-vibration, high-precision operation requirements. With these technological breakthroughs, HRB products fully cover the core components of various systems in the aerospace field, becoming a reliable “Chinese core” for 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 “Beluga 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”.
Since it started as a national key project during the “First Five-Year Plan” period, the indissoluble bond between HRB people and China’s aerospace industry has continued for more than 70 years. From manned space flight 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, and with solid technical accumulation and rigorous craftsmanship, it delivers excellent answers under extreme technical requirements.
After joining Jianlong Group in 2020, Jianlong Harbin Bearing’s innovative potential in the aerospace field has been further unleashed. 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 its 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 best every bearing for the aerospace industry” is a mission engraved in the genes of Harbin Bearing. 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, 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 support 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, deepening cooperation with aerospace research institutions, and increasing investment in intelligent manufacturing. It will help my country’s aerospace industry 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 technological accumulation to lay a solid foundation for the “Chinese bearings” of a great power’s heavy equipment.
Seventy-five years of original aspirations have been as firm as a rock, and seventy-five years of craftsmanship have been far-reaching. Looking to the future, Jianlong Harbin Bearing will continue to use innovation as an engine to climb to the top in the breakthrough of aerospace bearing technology, and with more excellent products and deeper accumulation, it will contribute more “Harbin Bearing Power” to my country’s progress from an aerospace power to a strong country, and let “Chinese bearings” shine more brightly in the journey of the stars and the sea.
