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 Technical specifications Operating temperature: -20 °C ➝ +280 °C NLGI grade: 2 DN factor (dm x n): 300,000 mm/min Base oil viscosity (40 °C): 510mm²/s Four-ball test rig (welding load): 9,000 N Applications 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.
