CHEVRON SRI GREASE 2
Chevron SRI Grease is a high temperature ball and
roller bearing grease.
Chevron SRI Grease 2 is a high temperature
ball and
Chevron SRI Grease 2 delivers value through:
•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
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
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 is recommended:
• for use in a wide range of automotive
and industrial
• for use in antifriction bearings
operating at high speeds (10,000 rpm and greater)
• where the operating temperatures are on
the order of 150°C (302°F) and higher
• where there is a likelihood that water
or salt water will get into the bearings
Chevron SRI Grease 2 will perform in
bearings at temperatures as low as -30°C (-22°F).
Chevron SRI Grease 2 is registered by NSF
and is acceptable as a lubricant where there is no possibility of
food contact (H2) in and around food processing areas.
The NSF
Nonfood Compounds Registration Program is a continuation of the
USDA product approval and listing program, which is based on
meeting regulatory requirements of appropriate use, ingredient
review and labeling verification

CHEVRON SRI GREASE2 Typical Test Data  Typical test data are average values only. Minor variations which do not affect product performance are to be expected in normal
manufacturing.
1 Minimum operating temperature is the lowest temperature at which a grease, already in place, could be expected to
provide lubrication. Most greases cannot be pumped at these minimum temperatures.
2 Maximum operating temperature is the highest temperature at which the grease could be used with frequent (daily)
relubrication.
* Determined on mineral oil extracted by vacuum filtration.
♦ Not tested at this temperature.
† Too stiff at this temperature to pump through device.
Minor variations in product typical test data are to be expected in normal manufacturing.
