Grease «LZ-TSNII» (GOST 19791-74) is low-viscosity petroleum oil solidified with soda-calcium soap of acids of castor oil. «LZ-TSNII» contains antioxidizing and antiwear additives.
Possesses good antiwear and antiscuff qualities, propensity to thermohardening, the weak water resistance, insufficient conservation properties. It is efficient at temperature -40 … +100°С.
Used in roller bearings of railway cars. Substitutes: «1-13 grease», «Litol-24@».

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
