Oil VNIINP-403 (GOST 16728-78) is distillate oil from sulphurous and low-sulphur, containing antioxidizing, anticorrosive and antifoamy additives.
Oil VNIINP-403 is intended for application as a working liquid for a volume hydrodrive of metal-cutting machine tools, automatic transfer lines, individual heavy presses and other industrial equipment, and also in circulating lubricant systems of metal-cutting machine tools and other mechanisms working on oil with similar properties.

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.
