GREASE
Black Pearl SRI® 2 (formerly known as SRI® Grease 2)
Black Pearl SRI® 2 is a specially formulated grease containing a highly refined paraffinic base oil, synthetic polyurea ashless organic thickener and high performance rust and oxidation inhibitors, for the lubrication of anti-friction ball, needle and roller bearings operating at speeds up to and above 10,000 rpm, operating at higher temperatures, or where water or salt water may penetrate bearings.

Benefits
Features
Applications
- Enhanced oxidation stability
Synthetic polyurea thickener is very oxidatively stable at elevated temperatures, This, coupled with its high dropping point and the highly refined base oil and high performance anti-oxidant components, enables operation for extended periods at high temperatures.
- Protects metal surfaces
Special rust and corrosion inhibitors provide protection to metal surfaces in wet conditions, even in a salt water environment. Passes Bearing Rust Test, ASTM D1743-73 with 5% synthetic sea water. Outstanding oxidation stability prevents the formation of corrosive oxidation by-products. oxidation by-products.
- Superior resistance to water washout
Synthetic polyurea thickener has excellent inherent water resistance.
