Oil I-40A

Oil И-40А (GOST 20799-88) is a distillate oil or a mix of distillate oil with residual oil from sulphurous and low-sulphur petroleums of selective clearing.
It used as working liquids in hydraulic systems of the machine-tool equipment, automatic transfer lines, presses, for greasing it is easy — also middlingloaded tooth gearings, slideways bearing and sliding of machine tools where it is not required special oils, and other mechanisms. Most widely apply oil I-40A in hydraulic systems of the industrial equipment, to the building, road and other machines working on open air.
Application specified oils in those or other mechanisms depends on their viscosity: in process of its increase in oil use in more loaded and less high-speed mechanisms. It is possible to replace the specified oil with alloyed oils IGP-18, IGP-30, IGP-38 and IGP-49 (TU 38.101413-97) corresponding viscosity.

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.
