The grease Lita (TU 38.101808-90) is low-viscosity petroleum oil solidified with a lithium stearate and a ceresin wax.
The basic operational characteristics: high water resistance, good conservation properties, low mechanical stability.
It is efficient at temperature-50 … +100°С. The Scope: friction units of machines and the mechanisms maintained open-air, mechanisms of the portable tool with an electric or mechanical drive.

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.
