Solid oil fatty (Solid oil ZH) (GOST 1033-79) is a general purpose grease; a mix of petroleum oils of average viscosity solidified with calcium soap of the fat acids which are a part natural (vegetative and animal) fats.
The basic operational characteristics: under the basic characteristics it is close to synthetic solid oils. It possesses the best is viscous-temperature properties, it is less condensed at storage. It is efficient at temperature-30 … +65°С, in powerful mechanisms (bearings, hinges, blocks, etc.) — from-50°S. The Scope: rough friction units in mechanisms and machines of vehicles, agricultural machinery; manual and other tool, screw and chain transfers and etc.
Appearance and colour: Homogeneous ointment without lumps from light yellow to dark brown colour

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.
