Black Pearl® SRI 2 is a high temperature ball and roller bearing grease.

Features

• Wide application range — Suitable for high rpm operation, operating temperatures ranging from -30°C to 177°C (-22°F to 350°F).
• Excellent oxidation stability — Provides exceptional bearing life at operating temperatures in the range of 93°C to 177°C (199°F to 350°F).
• Excellent rust protection — Provides rust protection as defined by ASTM D5969 with 10% Synthetic Sea Water.
• Chevron SRI Grease 2 is a high temperature ball and roller bearing grease. It is formulated with highly refined base stocks, a modern ashless, organic polyurea thickener coupled with high performance rust and oxidation inhibitors (the latter to provide outstanding rust protection in severe applications that many electric motor applications are exposed to in field operations). Its texture is smooth and buttery and its color is dark green.
• As noted, Chevron SRI Grease 2 passes the Static Bearing Rust Test, ASTM D5969, with 10% synthetic sea water. These properties help to provide longer bearing life under high speed and high temperature operation. This is nearly 10 times the life possible when using conventional lithium greases. Under normal operating temperatures and conditions, Chevron SRI Grease 2 can be used as a “Life Pack” lubricant in sealed bearings.
• Note that in today’s more modern, high output (horsepower), high load electric motors, there are times where these units employ ball bearings and roller element bearings on the same motor. On units where horsepower and load are considered high on the roller element bearing, EP greases should be employed. In these instances, Black Pearl® Grease EP would be the grease of choice and is fully compatible to use with Chevron SRI Grease 2.
