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 .

*Fretting-corrosion resistance test data

Because of its superior ingredients (namely a urea-based consistency enhancer), high-grade synthetic oil, and a special additive, AFC Grease provides high fretting-corrosion resistance.
The test data on the right-hand page compares AFC Grease with an ordinary bearing grease.
