Product Description lubrication for high-speed railway triansdoor systems on high-speed railway trains, underground railway trains and urban rail transit trains lubricant for trians industrymade by thickening special synthetic base oil with special fatty acid lithium soap thickener and blending anti-rust, anti-wear and anti-oxidation additives through a special process. It features low frictional resistance at low temperatures, good oil separation control ability and excellent stability.Specialized Lubricant for Rail Transit Door SystemsIn the operation of rail transit vehicles—including high-speed railway trains, underground railway trains, and urban rail transit trains—door systems are critical components that demand reliable lubrication to ensure smooth, quiet, and long-lasting performance. A high-performance lubricant tailored to these specific applications has emerged as a key solution, with a mechanism uniquely suited to meet the rigorous demands of rail door operationsThis lubricant's core mechanism is engineered to address the unique challenges of rail transit door systems. These doors undergo frequent opening and closing cycles—sometimes hundreds of times daily—exposing lubricants to repeated mechanical stress, vibration, and varying environmental conditions. While the lubricant excels in rail door applications, it is essential to note its usage limitations: this product is not suitable for use in rubber environments. Rubber components (e.g., door seals, gaskets) can react with the lubricant's chemical composition, leading to swelling, hardening, or degradation of the rubber. This not only compromises the rubber's sealing function but also risks contaminating the lubricant itself, reducing its effectiveness. Thus, it should be applied exclusively to metal surfaces within door systems, avoiding contact with any rubber partsAnother critical specification is the lubricant's wide application temperature range: -50℃ to 120℃. This range addresses the extreme temperature fluctuations rail vehicles encounter—from frigid winter conditions in northern regions (where temperatures drop below -30℃) to high-temperature environments in summer or inside train compartments (where heat buildup can exceed 50℃). Even at -50℃, the lubricant remains fluid enough to coat surfaces and reduce friction; at 120℃
