Railway grease LZ-TSNII
Railway grease LZ-TSNII is a low viscosity hydrocarbon oil, thickened with sodium-calcium soap of castor oil acids, contains antioxidant and antiwear additives.
The grease has excellent low-temperature properties, which allow operating of friction units under extreme conditions to a temperature of -60 ° C. The complex of extreme pressure and antioxidant additives, which are part of the grease, help on the formation of films that reduce the ultimate load, as well as the intensity of wear and, significatly, prevent galling at ultra-high loads.
