NSK Grease AS2



It is an environmentally friendly and widely used grease for high load application. It is mineral oil based grease containing lithium thickener and several additives. It is superb in load resistance as well as stability in oxidization. It not only maintains good lubrication over a long period of time, but also demonstrates superb capability in retaining water. Even containing a large amount of water, it does not lose grease when it is softened.


It is a standard grease for general NSK linear guides, ball screws, and monocarriers. It is prevalently used in many applications because of its high base oil viscosity, high load resistance, and stability in oxidization.
