Synthetic solid oil (Solid oil S) (GOST 4366-76) is a general-purpose grease. It is a mix of oils acid-alkaline (70 %) and selective (30 %) clearings thickened with calcium soaps of stillage bottoms SZHK-grease (S20 and above) and low-molecular SZHK-grease С5-С6.
The basic operational characteristics is good water resistance, colloid stability, protective properties, a narrow range of working temperatures and low mechanical stability. It is efficient at temperatures from-30 … +65°С, in powerful mechanisms (bearings, hinges, blocks, etc.) – from -50 °C
Application: rather rough friction assemblies of mechanisms and machines, vehicles, agricultural machinery; manual and other tool, hinges, screw and chain transfers etc.
Appearance and color: Homogeneous ointment without lumps from light yellow to dark brown color

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.
