Oil INSp-40 (TU 0253-007-00151911-93) is distilling, residual oil and a mix of distilling and residual oil oils from sulphurous petroleums of the selective clearing, containing anti-«stick-slip»additive, antiscoring additive, adhesive additive, solubilizationgv additives and antifoamy additives.
Apply to greasing directing slidings and slideway bearing of metal-cutting machine tools, transfers of a running screw-nut of machine tools of special high accuracy, with programmed control, heavy and others where uniformity of slow movings is required, accuracy and sensitivity of adjusting movings of tables, supports, ползунов, grandmas, racks and other knots and also where it is necessary to lower level of factors of a friction in static and kinetic conditions.
Oil INSp-40 apply to greasing easily — and sredne — loaded horizontal directing. Except basic purpose INSp it is possible to use for greasing of other knots of machine tools, such, as gear and worm gears, cams, ratchet mechanisms.
Density at 20°С, kg/m3, no more: 908
Viscosity kinematic, cSt, at 40°C, not less: 50-70
Flash temperature, in an open crucible, °C, not more low: 190
Hardening temperature, °C, not above: -20
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 influence work of components.
