Recently, Sinopec Great Wall Lubricant achieved a major technical breakthrough in the field of axle-box bearing lubricants, successfully securing patent authorization for its independently developed technology under patent number CN202211055068.0. This innovative axle-box bearing lubricant composition-along with its associated preparation method-not only optimizes the extreme-pressure and anti-wear additive system but also represents a significant leap forward in enhancing overall product performance.
As a critical material for lubricating the sliding axle-box bearings of internal combustion locomotives within the coal industry, the performance of axle-box bearing lubricant directly impacts the operational stability and reliability of these locomotives. In practical applications, traditional axle-box bearing lubricants often face challenges such as insufficient extreme-pressure and anti-wear capabilities, excessive sludge formation, and poor low-temperature performance and oxidation stability. Addressing these pain points, the R&D team at Sinopec Great Wall Lubricant dedicated itself to intensive research, successfully developing a brand-new axle-box bearing lubricant composition. This composition utilizes a specialized extreme-pressure and anti-wear additive system that effectively enhances the lubricant's load-bearing and anti-wear properties while minimizing sludge formation, all while maintaining excellent low-temperature performance and oxidation stability.
Today, this innovative achievement has been successfully commercialized as the "Great Wall No. 1" and "Great Wall No. 2" Axle-Box Bearing Lubricants, providing robust support for the stable operation of internal combustion locomotives throughout the coal industry.
