Extreme-temperature bearing grease for use at high loads and temperatures.
Areas of application
Grease lubrication of friction and rolling bearings in the high-temperature range up to 300°C
Lubrication of tunnel kiln cars, baking, burn-in and drying furnaces, hot gas units, reaction vessels, boiler plants, roller and conveyor rollers in continuous furnaces, etc.
Use at bearing points under influence of chemicals
Lubrication of bearings under influence of fuel
Advantages and benefits
Absolutely resistant to water and steam
Resistant to solvents, for example benzene, benzol, acetone, trichloroethylene and against inorganic acids, for example sulphuric acid, hydrochloric acid and nitric acid as well as stearic acids, alcohols and halogens
Broad range of applications above the temperature limits of other lubricating greases
Excellent wear protection
Reduced maintenance and lubricant costs due to possible lifetime lubrication
Excellent plastic and elastomer compatibility

Thorough cleaning of the bearings from other lubricants, for example with OKS 2610/OKS 2611 universal cleaning agent is imperative. Subsequently blow out with dry air. Before filling for first time, remove anti-corrosion agent. Fill the bearing such that all functional surfaces are certain of being greased. Fill bearings running slowly completely, fill high-speed bearings (DN value > 150,000) only up to about 2/3 of the free space inside the bearing.
