Oil ILS-5 (TU 38.1011191-97) (in exchange ИГП-4, ИГП-6, ИГП-8, ИГП-14) — distillate oil from sulphurous petroleums of deep selective clearing with antioxidizing, antiwear, anticorrosive and antifoamy additives.
Are intended for high-speed шпиндельных sites of metal-cutting machine tools. Apply to greasing of high-speed mechanisms (spindles, bearings and the connections interfaced to them). Oil ILS-5 economically is the most expedient for using instead of oils corresponding on viscosity without additives — I-5A and I-8A.

Viscosity kinematic, cSt, at 40°С, not less: 4
Mass fraction of zinc, %, not less: 0.04
Mass fraction of sulphur, %, not less: 0.9
Flash temperature, in an open crucible, °C, not more low: 110
Hardening temperature, °C, not above:-15

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.
