MG-8A

Composition: represents a mix of distillate and residual components with addition of depressant, antifoam and multicomponent (improving antioxidizing, anticorrosive and dispersing characteristics) additives. Possesses high enough level of wear-protective properties.

Applications: the oil is used is in hydraulic systems of the hinged equipment and a steering of tractors, self-propelled agricultural cars and dumping cars. Earlier not enough such structure was produced in accordance with GOST 10541-78 under mark of engine oil М-8А for the engines carburetor.

MGE-10A

Oil MGE-10А (GOST 38 01281-82) — the dearomatized low cold-test fraction received from hydrocracking products of a mix paraffinic petroleums. Contains thickening, antioxidizing, anticorrosive and wear-protective additives.
This oil is intended for operating in a range of temperatures from — (60-65) °C to + (70-75) °C.

Color: light brown, transparent
Density at 20°С, kg/ cu.m, not more than: 860
Kinematic viscosity, cSt, at 50 °C, not less than: 10
Kinematic viscosity, cSt, at 40 °C, not less than: —
Kinematic viscosity, cSt, at -50 °C, not less than: 1500
Acid number, mg, not more than: 0
Flash temperature, in an open cup, °C, not lower than: 96

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 work of components.

NGZH-4u

Working liquid NGZH-4u is synthetic flame safety a liquid on the basis of aethers of phosphoric acid. It has been created liquid NGZH-4 in exchange earlier widely applied in aircraft calling erosion of valves of hydrosystems and, as consequence of it, liquid leak. Liquid NGZH-4u is erosion-resistant liquid, contains the additives improving it вязкостные, antierosive, antioxidizing properties. It is efficient in the range of temperatures from -55 to 125 °C at working pressure to 21 megapascal. Has temperature of spontaneous ignition 650-670 °С, slowly burns in a flame, but does not sustain combustion and does not extend a flame unlike oil liquids of type АМГ-10. Is good softener and solvent for many nonmetallic materials, therefore at use of the last in contact to liquid NGZH-4u it is necessary to check carefully their compatibility or to use only those materials which are picked specially up and recommended for liquids of type NGZH.

RMC

The distillate oil received from naphthene petroleums, possesses the improved greasing properties. Apply in the independent hydrodrives of a special purpose maintained at an ambient temperature from -40 to +55 °C.

7-50C-3

Working liquid 7-50C-3 (GOST 20734-75) is the synthetic liquid made of a mix polysiloxane of a liquid and an organic aether with addition antiwear of an additive and inhibitors of oxidation.
Apply in hydraulic units and hydraulic systems of flying machines in a range of temperatures from-60 to +175°С it is long with overheats to 200°С, working pressure to 21 megapascal.

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.
