Grease LZ-CRI
rail lubrication
Description
Lubricant LZ-CRI – low-viscosity petroleum oil thickened with soda-calcium soap of castor oil acid contains antioxidant and antiwear additives. LZ-CRI has good antiwear and extreme pressure properties, a tendency to thermal hardening, poor water resistance, insufficient conservation properties.
within the temperature range -60 … + 100 ° C. Since 1999, the railway LZ-CRI lubricant manufactured for RZD only for TU 0254-013-00148820-99 called grease LZ-CRI (I).
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.
