Product DescriptionLubrication for High-Speed Railway TrainsDoor systems on high-speed railway trains, underground railway trains, and urban rail transit trains Lubricant for Trains IndustryCrafted using special synthetic base oil thickened with fatty acid lithium soap and blended with anti-rust, anti-wear, and anti-oxidation additives, this lubricant offers low frictional resistance at low temperatures, excellent oil separation control, and superior stability.Specialized Lubricant for Rail Transit Door SystemsIn rail transit vehicles like high-speed, underground, and urban rail trains, door systems are vital components that require dependable lubrication to ensure smooth, quiet, and long-lasting operation. A high-performance lubricant tailored for these specific needs stands out as a key solution, uniquely meeting the rigorous demands of rail door operations.This lubricant's core engineering is designed to tackle the unique challenges of rail transit door systems, which undergo frequent opening and closing cycles—sometimes hundreds daily—subjecting lubricants to repeated mechanical stress, vibration, and diverse environmental conditions. While excelling in rail door applications, it's crucial to note the lubricant's limitations: it is unsuitable for rubber environments. Rubber components, such as door seals and gaskets, may react with its chemical composition, leading to swelling, hardening, or degradation, compromising sealing function and risking lubricant contamination. Apply exclusively to metal surfaces within door systems, avoiding rubber contact.Another vital specification is the lubricant's extensive application temperature range: -50℃ to 120℃. This range addresses the extreme temperature variations rail vehicles face—from freezing winter conditions in northern areas (with temperatures dropping below -30℃) to high heat environments in summer or inside train compartments (where heat can exceed 50℃). Even at -50℃, the lubricant remains fluid to coat surfaces and reduce friction; at 120℃
