Original Grease AFJ Grease

AFJ grease uses refined mineral oil as its base and a urea-based grease as its consistency enhancer, while also featuring other special additives. This gives it excellent lubrication properties at a wide range of speeds—from low to high.

  • High load
  • Machine stability
  • For a wide range of speeds
  • Micro-vibration
  • For sliding friction
  • Ulea-based
