Lubemater RM-W wheel set bearing grease
Lubemater RM-W wheel set bearing grease is refined from high-performance synthetic oil as the base oil, special metal soap as the thickener, and supplemented with a variety of high-performance additives. It is a high-performance grease specially developed for lubricating the wheel set bearings of railway locomotives. It can meet the harsh lubrication requirements of locomotive wheel set bearings, such as extreme pressure load, water resistance and long service life.
It is applicable to speeds not exceeding 160km/h and axle loads not exceeding 25 tons. Lubrication of wheel set bearings and rolling lock bearings for imported and domestic railway and electric locomotives (including EMUs) with a speed not exceeding 200km/h and an axle load not exceeding 23 tons.
The operating temperature range is: -40℃ to 120℃.
10kg/50kg
Core Advantage
1. Good shear stability ensures no oil flaking during long-term use
2. It has a long service life and can be used for 8 years or 800,000 kilometers in well-sealed truck rolling bearings
3. Excellent extreme pressure and anti-wear performance ensure the safe operation of the vehicle under heavy-load working conditions
