NSK Grease General High-
load

NSK Grease AS2 Reference no. : NSK GRS AS2
Quantity: 80 g Tube color: Brown

Feature It is an environmentally friendly and widely used grease for high load application. It is mineral oil
Application 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.
