AFC潤滑脂是使用了高級合成油作基油的尿素系增稠劑和特殊添加劑的，因此具有出色的耐微動磨損性。

★特性

1.	出色的微磨損性是新開發出的能充分發揮出色的耐微動磨損效果的潤滑脂。
2.	長壽命潤滑脂與一般的金屬肥皂基潤滑脂不同，具有出色的氧化安定性，可長期間使用，從而能減輕保養的負擔。
3.	適用溫度範圍廣泛的潤滑脂因基油使用了高級合成油，在–54℃~ +177℃的廣泛溫度範圍內能發揮良好的潤滑特性。

AFC Grease has high fretting-corrosion resistance due to a special additive and a urea-based consistency enhancer which uses a high-grade synthetic oil as the base oil.

*Features

1.	High fretting-corrosion resistance AFC Grease is designed to be highly effective in preventing fretting-corrosion. The following test data explains why this is so.
2.	Long service life Unlike ordinary metal soap-based greases, AFC Grease exceeds in antioxidation stability and therefore can remain in service for a long 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 good over a wide range of temperatures from -54 ℃to +177 ℃.
