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.

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

Features

Features

  • Wide range of speeds
    It provides consistent and even lubrication at a wide range of speeds, from low to high.
  • Wear resistance
    Even at low speeds, it has excellent oil film formation to reduce wear.
  • Vibration resistance
    It reduces wear caused by machine vibration during high-speed operation.
