High Temperature Bentonite Lubrication Grease , thickened with extra high performance kiln, designed for high speed and high temperature applications, or for lubrication of sliding and ball bearings exposed to variable working conditions from normal to high temperatures. Unlike conventional soap thickener, it is not melting at high working temperatures thanks to its clay thickener.

High Temperature Bentonite Lubrication Grease, made from high quality and high viscosity mineral base oil. It is specially formulated to provide excellent resistance to low evaporation and oxidation at high temperatures, excellent water washout resistance, high performance against corrosion at low speeds and heavy loads applications.

Performance Features:
It offers good protection against corrosion and high working temperatures;
Leakage is prevented in the bearing and the grease is stable in its consistency;
Excellent water washout and steam resistance;
Excellent stability against high and variable working temperatures.

Furnace conveyor chain bearings;
Slag and hot metal car wheel bearings;
In glass industry in conveyor band roller bearing;
Camshafts, slides and other sliding machine elements.

36 months shelf life recommended, as it is stored properly in its original, sealed container.
