THK Original Grease AFB-LF Grease

AFB-LF Grease is a general-purpose grease that provides excellent extreme pressure performance and mechanical stability properties through the use of a refi ned mineral oil base oil and a lithiumbased consistency enhancer.

Features

• Extreme pressure resistance

The action of the special additives provides higher wear resistance and extreme pressure resistance than other lithium-based greases available on the market.

• Mechanical stability

AFB-LF Grease is not easily softened and demonstrates excellent mechanical stability even when used for a long period of time.

• Long service life

It provides many times the lubrication life of general lithium soap-based greases. As a result, it offers a lower maintenance workload and greater economy due to the longer intervals between greasing.
