Grease VNIINP-273 (TU 38.1014767-74) is a synthetic hydrocarbonic oil solidified with inorganic thickeners. It contains antioxidizing, anticorrosive additives and the antifrictional additive.
It possesses good antiscuff properties, colloid and chemical stability. It have a soft consistence. It is efficient at temperature -20 … +120°С.
Scope: rolling and sliding bearings, ballscrew-nut transmissions, rack-and-pinion drives and screw drives, the carving connections working in the conditions of influence of radiation. A substitute — ВНИИНП-275.

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.
