June 6, 2025- With the global industry accelerating towards intelligent and extreme environmental applications, bearing lubrication technology, as the "blood" of mechanical equipment, is ushering in a critical breakthrough. Recently, a new generation of wide temperature lubricating grease technology jointly launched by multiple domestic bearing enterprises and research institutions has achieved stable lubrication in the extreme temperature range of -70 ℃ to+260 ℃, marking China's breaking of the international technological monopoly in the field of high-end bearing lubrication and providing core support for strategic industries such as aerospace, polar scientific research, and deep-sea equipment.
Technological Breakthrough: From 'Neck Jam' to 'Leader'
For a long time, bearing lubrication technology in extreme environments has been monopolized by a few international giants. Traditional lubricating grease is prone to solidification at low temperatures and oxidation at high temperatures, leading to frequent equipment failures. The new generation of wide temperature lubricating grease represented by B.GREEASE-5052/LR achieves three core advantages of "high drop point, low starting torque, and long service life" through the synergistic effect of fully synthetic base oil and special composite thickener, combined with multiple additives such as extreme pressure anti-wear, anti-oxidation, antifreeze, and anti-corrosion.
Low temperature performance: The lubricating grease can still maintain fluidity in an environment of -70 ℃, ensuring the normal operation of polar scientific research equipment and wind turbine bearings in high-altitude regions;
High temperature stability: At a high temperature of+260 ℃, the lubricating grease does not soften or lose, making it suitable for extreme working conditions such as aerospace engines and nuclear power equipment;
Long term protection: By enhancing adhesion, reducing grease loss, extending equipment maintenance cycles, and lowering overall lifecycle costs.
According to test data, this technology enables the bearing wear life to reach more than three times the international standard, reduces the failure rate by 60%, and provides a solid guarantee for the reliability of high-end equipment.
Application scenario: Full coverage from deep sea to space
The breakthrough of the new generation of wide and warm lubricating grease has directly promoted the upgrading of multiple strategic industries:
Aerospace: In equipment such as satellites and rocket engines, lubricating grease needs to withstand severe vibrations during launch and extreme temperature differences in space. The bearings provided by Luozhou Group for the "Shenzhou" series spacecraft have successfully passed rigorous tests simulating space environments after adopting this technology.
Polar scientific expedition: The motor bearings of the low-temperature liquid transfer pump on China's "Xuelong" scientific expedition ship have been running continuously for 18 months without any faults in the -50 ℃ Antarctic environment, and the lubricating grease performance is stable.
Deep sea equipment: In 10000 meter deep sea probes, lubricating grease needs to withstand high pressure, low temperature, and strong corrosive environments. The deep-sea bearing lubrication solution jointly developed by Changsheng Bearing and the Chinese Academy of Sciences has been applied to the manned submersible "Striver".
New Energy and Robots: In humanoid robot joints and electric drive systems for new energy vehicles, the high temperature resistance and low noise characteristics of lubricating grease significantly improve equipment efficiency and user experience.
Industrial synergy: from technological breakthroughs to ecological construction
Technological breakthroughs cannot be achieved without collaborative innovation in the industrial chain. Luozhou Group, Changsheng Bearing and other enterprises have deeply cooperated with scientific research institutions such as the Chinese Academy of Sciences and Tsinghua University to build a full chain innovation system of "basic research engineering industrialization". For example, Changsheng Bearing has successfully reduced the friction coefficient of the bearing to below 0.02 through the research and development of polymer self-lubricating materials, reaching an international leading level.
Meanwhile, the empowerment of digital supply chains has accelerated the implementation of technology. Zhenkunxing Industrial Supermarket has reached a strategic cooperation with Luozhou Group to quickly promote the new generation of lubricants to fields such as construction machinery and rail transportation through a digital procurement system and a national warehousing and logistics network, covering over 100000 small and medium-sized customers.
Future outlook: the 'hidden champion' of trillion dollar markets
According to industry predictions, by 2030, the global high-end bearing market will exceed one trillion yuan, with lubrication technology accounting for 30%. Chinese enterprises are transforming from "bearing manufacturers" to "system solution providers", seizing the high-end of the global value chain through the deep integration of lubrication technology, material science, and intelligent manufacturing.
We not only need to sell bearings, but also define the standards for the future manufacturing industry, "said Chu Chenjian, General Manager of Changsheng Bearing. The company has laid out the second growth curve of humanoid robot actuators, nuclear power bearings, and strives to become a leading global supplier of core components.
Conclusion
From Shenzhou spacecraft to polar scientific research, from deep-sea exploration to intelligent manufacturing, every breakthrough in bearing lubrication technology is reshaping the boundaries of industry. The birth of a new generation of wide and warm lubricating grease is not only a "hardcore counterattack" made in China, but also a microcosm of global industrial civilization progress. In the future, with the continuous iteration of technology, China's bearing industry will write more legends of "invisible champions" on the global stage.
