Original Grease AFC Grease
AFC grease uses high-grade synthetic oil as its base and a urea-based grease as its consistency enhancer, while also featuring special additives. This gives it excellent fretting resistance.
Features
Features
- Fretting resistance
It is designed to be highly effective in preventing fretting corrosion. - Wide temperature range
Since a high-grade synthetic oil is used as the base oil, the lubricating performance remains high over a wide range of temperatures, from ‒54℃ to 177℃.
