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.
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.
