Grease «LKS-2» (TU 38.101015-85) is a mix of synthetic oils solidified with complex lithium soap. Grease «LKS-2» contains antioxidizing and anticorrosive additives.
It is characterised by the high mechanical, colloid, antioxidizing and thermal stability, the raised antiwear properties.
It is efficient at temperature-40 … +150°С.
Score: bearing units of the main spindles of the metal-cutting machine tools equipped with ball and roller bearings. A substitute is KBS.

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.
