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.

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.

The grease Aerol (TU 38 USSR 201171-79) on  structure  is like to grease Grafitol, but instead of graphite contains disulfide of molybdenum. It possesses the raised antiscuff and antiwear properties, high thermal stability and water resistance. The grease Aerol is efficient at temperature -25°С…+160°С. The Scope: bearings of traction chains of conveyors in drying chambers, friction units of distributing furnaces of pig-iron moulding and other mechanisms working at raised temperatures. A substitute is Grafitol.
