The grease VNIINP-271 (TOR 38.101603-76) is a difficult ether thickened with lithium soap of stearin acid and acids of the hydrogenated castor oil. It contains antioxidizing and wear-protective additives.
The grease VNIINP-271 possesses good wear-protective and antiscuffing properties, low colloid and high antioxidizing stability, good frost resistance.
It is efficient at temperatures from -60 °С…+130 °С.
The application: ball-bearings with frequency of rotation to 30000 mines-1, and also with the small moment of a friction.

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 mechanical-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.
