Product DescriptionLubrication for High-Speed RailwaysDoor systems on high-speed trains, subways, and urban transit railways Lubricant for Train IndustryFormulated by thickening a special synthetic base oil with a fatty acid lithium soap thickener and blending in anti-rust, anti-wear, and anti-oxidation additives using a proprietary process. It ensures low friction at low temperatures, excellent oil separation control, and outstanding stability.Specialized Lubricant for Rail Door SystemsIn rail transit vehicles, including high-speed, subway, and urban railways, door systems are crucial for smooth, silent, and durable operation. A high-performance lubricant designed for these applications has become vital, offering a mechanism expertly suited to rail door demands.This lubricant's core mechanism is crafted to tackle the unique hurdles of rail door systems. These doors endure frequent cycles—sometimes hundreds daily—subjecting lubricants to mechanical stress, vibration, and diverse environmental conditions. While the lubricant is excellent for rail doors, it should not be used in rubber environments. Rubber parts like seals and gaskets can react adversely with the lubricant, causing swelling, hardening, or degradation. This affects the rubber's sealing function and may contaminate the lubricant, reducing its efficacy. It should be used solely on metal surfaces, avoiding rubber contact.Another important specification is the lubricant's wide temperature range: -50℃ to 120℃. This addresses the extreme temperature changes in rail vehicles—from harsh winters in northern regions to high heat in summer or train interiors. Even at -50℃, it stays fluid to coat surfaces and reduce friction; at 120℃
