Cardan grease «AM» (TU 38.5901302-91) is a petroleum oil of average viscosity solidified with a soda soap, acid of cotton-seed oil, acid of castor oils and rosin. It is characterised by low mechanical stability, ability to be washed away from friction units.
It is efficient at temperature-10 … +100°С. The Scope: hinges cardan  constant angular speed of forward leading bridges of cars. Substitutes: SHRUS-4, LITOL-24.

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.
