Lubricating grease 4220

PFPE-basedfor bearingsfor the chemical industry

Extreme-temperature grease on the basis of perfluorinated polyether oils (PFPE) for use in food processing technology at maximum loads and temperatures. Areas of application Application, for example at 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/fuel Advantages and benefits Extraordinary resistance to chemicals, for example to solvents, for example benzene, benzol, acetone, trichloroethylene and against inorganic acids, such as sulphuric acid, hydrochloric acid and nitric acid as well as stearic acids, alcohols and halogens Excellent plastic and elastomer compatibility Broad range of applications above the temperature limits of other lubricating greases Reduced maintenance and lubricant costs due to possible lifetime lubrication NSF H1 registered MOSH/MOAH-free Technical specifications consistency: 2 NLGI grade (DIN ISO 2137) viscosity at (40°C): 390 mm²/s four-ball test rig welding load: > 10,000 N Applications Thorough cleaning of the bearings from other lubricants, for example with OKS 2610/OKS 2611 universal cleaner 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.
