THK-AFC
AFC Grease has high fretting-corrosion resistance due to a special additive and a urea-based consistency enhancer using a high-grade synthetic oil as the base oil.
[Features]
(1) High fretting-corrosion resistance AFC Grease is designed to be highly effectivein preventing fretting corrosion.
(2) Long service life Unlike ordinary soap based grease for metallubrication, AFC Grease excels in antioxidation stability and therefore can be used for a long period of time. As a result, maintenance
work is reduced.
(3) 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 ℃.
