CHEVRON BLACK PEARL SRI 2 14 oz tube # 254521643 Electric Motor Bearing Grease
A Chevron company product SRI GREASE 2
ELECTRIC MOTOR BEARING GREASE
High Temperature Electric Motor 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 superior
rust protection in severe applications that many
electric motors applications are exposed to
in field operations). Its texture is smooth and
buttery and its color is dark green.
SRI Grease 2 is Chevron’s preferred electric motor bearing grease.
Customer Benefits
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 exceptional rust protection as defined by Bearing
Rust, ASTM D5969 using 10% Synthetic Sea Water. Also does
extremely well on the Dynamic Bearing Rust (EMCOR) Test,
ASTM D6138 using 10% Synthetic Sea Water.
SRI GREASE 22Always confirm that the product selected
is consistent with the original equipment
manufacturer’s recommendation for the
equipment operating conditions and
customer’s maintenance practices.
SRI Grease 2
Applications
As noted, Chevron SRI Grease 2 passes the Bearing Rust Test, ASTM D5969 with
10 percent synthetic sea water. These properties help to provide longer bearing life under
high speed and high temperature operation than most other widely used antifriction
bearing greases. High Temperature Bearing Life, ASTM D3336, testing shows that the
life of a 204 K bearing lubricated with Chevron SRI Grease 2 and operating at
150° C (302° F) and 10,000 rpm is about 3,000 hours. 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, Chevron
Black Pearl® Grease EP would be the grease of choice and is fully compatible to use with
Chevron SRI Grease.
Chevron SRI Grease 2 is recommended:
• For use in a wide range of automotive and industrial applications
• 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 bearing
components
It performs satisfactorily in bearings at temperatures as low as -30°C (-22°F).
Applications where Chevron SRI Grease 2 will outperform most other greases include:
• As a “Life-Pack” lubricant by manufacturers of automotive generators, alternators, and
starters to protect against the effects of moisture and road-splash (factory-filled for life
ball bearings)
• Bearings on air-conditioning units in homes and other buildings
• Unsealed electric motor bearings operating under moist conditions
• Applications where silent operations are beneficial
Chevron recommends SRI Grease 2 to be used in the following OEM products:
• Bearing manufacturers: NSK, NTN, FAG, NMB, Timken, and Koyo.
• Electric motor manufacturers: Reliance Electric Company, U.S. Motors Division
of Emerson Electric Company, Toshiba International and Lincoln Motors.
