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superceded by Black Pearl SRI 2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

Recommended Uses
SRI Grease can be used in temperatures ranging from –20 to 140°C for continuous service. However, for short term exposure temperatures should not exceed 150°C. Applications can include high speed bearings operating under high or low temperature conditions, unsealed bearings where there is the likelihood of fresh or salt water getting into the bearings, sealed-for-life bearings, industrial ball and roller bearings, electric motor, fan, and air-conditioning unit bearings, automotive alternator, generator and starter motor bearings, water pump bearings and boat trailer wheel bearings. Operating temperature: -20°C up to 140°C, with short peaks up to 150°C.
Operating temperature: -20°C up to 140°C, with short peaks up to 150°C.
SRI Grease Is Recommended For Use In:
DIN 51502 KU2-20+140M+100
ISO 6743-9 L-XBDFA2L-XBDFA2
Performance Benefits
1. Enhanced Oxidation Stability
Synthetic polyurea thickener is stable at elevated temperatures.
Coupled with a high dropping point, highly refined base oil and anti-oxidant components, this enables extended operation periods at high temperatures.
2. 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. Good oxidation stability prevents the formation of corrosive oxidation by-products.
3. Superior Resistance to Water Washout
Synthetic polyurea thickener has inherent water resistance.
