Limol

The grease Limol (TU 38 USSR 201146-80) is a high-viscosity petroleum oil solidified with modified silicagel or a lithium hydroxyproline; contains a molybdenum disulfide, a metal oxide.
The basic operational characteristics: exclusively high antiscuff properties. It is efficient at temperature-50 … +300°С. The Scope: simplification of assemblage, extra earnings and greasing of bearings of sliding, hinges gear and screw gears, heavy duty slow-speed friction units, carving connections.

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.

VNIINP-225

The grease VNIINP-225 (GOST 19782-74) is an organosilicon liquid, solidified with a highly dispersed disulfide of molybdenum; contains stabilising additive.
The basic operational characteristics: it is efficient at temperature-60 … +250°С (aluminium alloys),-40 … +300°С (low-speed friction units). The Scope: mobile and motionless carving connections, heavy duty slow-speed friction units.
