The grease Grafitol (TOR 38 USSR 201172-77) is a petroleum residual oil. It contains graphite.
The grease Grafitol possesses high thermal stability, low evaporation, good antiscuffing properties, satisfactory water resistance. It is efficient at temperatures from -25 … +160 °С. Application: high-temperature friction assemblies, mainly slidings; hot fans, loops locks of drying chambers doors and other industrial mechanisms. A substitute product is Aerol.

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.
