Oil I-12A (GOST 20799-88) is distillate oil, produced is from sulfurous petroleums of selective clearing. Serves for greasing of plugs, bearings of spindles roving and other machines, sites full-fashioning and looping machines, spindles of the metal-cutting machine tools working with frequency of rotation to 5 thousand of mines-1, for directing grandmas of filler-boring, filler-polishing and other machine tools, for bearings of low-power electric motors with ring system of grease, as working liquids in the volume hydro drives working indoors and outdoors for piston group of ammoniac compressors and for many other things equipment kinds.
The oil is also used for manufacturing of oils with additives, plastic antifriction and conservation greases, emulsifying structures, technological greases and liquids.

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 the work of components.
