Extreme-Temperature Bearing Grease (OKS 4220) by OKS Spezialschmierstoffe GmbH

Product inquiry  

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
  • Grease lubrication of friction and rolling bearings in the high-temperature range
  • 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
  • Maximum water and steam resistance
  • 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
  • For long-term lubrication of lubrication points subjected to high pressure up to 280°C
  • 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 (as per recipe)
Technical specifications
  • lower operating temperature: -40 °C (< 1,400 hPa)
  • upper operating temperature: 280 °C
  • consistency: 2 NLGI grade (DIN ISO 2137)
  • viscosity at (40°C): 390 mm²/s (base oil)
  • four-ball test rig welding load: > 10,000 N
