National Grease EP series is extreme pressure lithium soap grease, which contains oxidation, rust and corrosion inhibitors and provides excellent EP properties. The use of a lithium soap base ensures effective resistance to softening under severe working conditions, efficient water resistance and a consistency, which remains relatively constant over the recommended range of operating temperatures. National Grease EP is non-corrosive to both steel and copper. The latter is of importance because of the use of bronze cages in many anti-friction bearings. The grease exhibits effective resistance to bleeding and superior resistance to water washout.
Benefits
- Superior lubrication under heavy and shock loading.
- Excellent load carrying ability.
- Excellent resistance to water washing.
- Effective rust protection and corrosion resistance.
Applications
National Grease EP is recommended for lubrication of plain and rolling element bearings in normal through heavy-duty industrial applications. It is suitable where loads are high or fluctuating in nature. The softer grades are particularly suitable for use in centralized lubrication systems. Can be used for both automotive and industrial applications.
