rail lubrication
Description
Grease VT-72
Applications
Lubrication VT-72 is used for lubrication avtotormoznyh devices of railway rolling stock (locomotive brake by friction of rubber on metal).
Advantages
- Lubrication VT-72 is a silicone fluid, thickened with complex calcium soap of stearic acid and acetic acid; contains an antioxidant additive and an additive that lowers the viscosity at low temperatures;
- Lubrication VT-72 has a high resistance to frost; does not cause swelling of rubber seals avtotormoznyh devices;
- Lubrication VT-72 is operable in a temperature range of from -60 ° C to +120 ° C (briefly to 150 ° C).

Grease LZ-CRI
Applications
Grease CRI-RS – is intended to protect against ice deposits on the current collectors of electric rolling stock and catenary wires in icing period. Temperature range lubricant is from plus 40 to minus 65 ° C. The lubricant is a blend of petroleum and synthetic oils thickened with lithium soaps of fatty acids containing deicing components, antioxidant and anticorrosion additives.
