The grease VNIINP-223 (GOST 12030-80) is a dioctyl sebacate thickened with complex soda soap. It contains antioxidizing and wear-protective additives.
The grease VNIINP-223 is defined by high degree of clearing. It is efficient at residual pressure 13.3 Pas and temperatures from -45 °С…+150 °С.
Application: special high-speed ball bearings with frequency of rotation to 60000 mines-1, bearings of sliding and low-power tooth gearings. A substitute product is VNIINP-228.

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.
