Rail Transit Lubrication Solutions
Drive the Green Future
Provides a full-vehicle biodegradable lubrication solution for rail transit vehicles—including high-speed trains, EMUs, subways, and light rail—covering core systems such as gearboxes, traction motors, bogies, air conditioning units, and doors.

Rail Transit Lubrication Challenges
- High-speed operation of high-speed train gearbox generates excessive heat, causing lubricating oil to oxidize and degrade, which accelerates gear wear.
- Urban rail transit vehicles undergo frequent start-stop cycles, subjecting traction motor bearings to alternating loads and causing lubricant loss.
- Rail vehicles operate in diverse environments, from extreme cold in the north to high heat in the south. Lubricants must perform reliably across a wide temperature range.
- Rail transit demands extremely high safety standards; lubricants must meet strict fire resistance and flame retardancy requirements.
