| Basic characteristics |
Smifluid special water-resistant railway grease designed for the protection of wheel pair flanges and rail from wear. The grease is applied on wheel flanges and side face of rails using on-board, track lubricators, as well as mobile rail lubricators. Oparating temperature range is from -50°С to +100°С. |
Semifluid spescial water-resistant railway grease designed for the protection of wheel pair flanges and rails from wear. The grease is applied on wheel flanges and side face of rails using on-board, track lubricators, as well as mobile rail lubricators. Operating temperature range is from -40°С to +120°С. |
It is used in cylindrical and planetary reduction gearboxes and motor reduction units operating with maximum specific engagement loads of up to 2000 MPa, requiring the application of high-quality reduction gearbox lubricants with a long service life. Operating temperature range is from -35°С to +120°С. |
