NLGI #0, #1 and #2
PRODUCT DESCRIPTION
AMSOIL GL Series multi-purpose, EP greases
are qualified against the highest grease standards*, NLGI
GC (wheel bearing) and LB (chassis), and are designed for
multiple use applications. These greases are composed of
synthetic base oils and lithium complex thickeners that
provide the film strength, shear resistance and mechanical
stability required for good grease lubrication. This combination
excels in high and low operating temperature ranges by providing
excellent oxidation stability, high temperature dropping
points, good low temperature torque values and good low
temperature pumping capabilities. The GL Greases are compounded
with an effective oil soluble extreme-pressure additive
for heavy loads, plus oxidation and corrosion inhibitors
that impart good oxidation stability and rust protection.
AMSOIL’s top performing lithium complex
thickener system provides excellent adhesion properties
and water resistance as identified by ASTM D-1264 water
washout test. This resistance to water means a protective
film of lubricant remains present to protect equipment against
wear while the corrosion inhibitors prevent rust. AMSOIL
GL Greases adhere to metal in all types of environments
and they resist squeeze out during operation. These qualities
ensure maximum lubricant protection during harsh operations.
AMSOIL GL multi-purpose greases are recommended
for many different applications. Its diversity simplifies
lubricant inventories and prevents greasing errors while
providing problem-free operation. AMSOIL GL Greases reduce
repair and maintenance costs.

APPLICATION RECOMMENDATION
AMSOIL GL Greases grades #0, #1 and #2,
are recommended for use in manual or automatic lubricating
systems. NLGI #0 (GLA) and #1 (GLB) have better mobility
and are the preferred choice for colder applications, for
automatic lubrication systems with long pumping runs, and
for gear box applications (where recommended by manufacturer).
NLGI #2 (GLC) is the preferred choice for medium to high
ambient temperatures, sleeve type bushings, high shock loading
environments, wet environments. and is the primary choice
for wheel bearings.
The correct consistency grade of AMSOIL
GL multi-purpose greases are recommended for use in heavy
and light duty applications found in manufacturing plants,
automotive applications, agricultural equipment and construction
equipment. These include, but are not limited to, roller
bearings, plain bearings, thrust bearings, gears, electric
motors, presses, winches, bushings, wheel bearings. chassis
lubrication, universal joints, ball joints, tie-rod ends,
and steering knuckles. AMSOIL GL greases are suitable for
use up to 350 F When operating at elevated temperatures,
frequent regreasing may be required.
AMSOIL GL Lithium Complex Greases are compatible
with many other types of greases. However, it is recommended
that when changing greases, the equipment be cleaned of
the old grease when possible or flushed with a liberal amount
of the GL grease while the mechanism is in operation. Closely
monitor the system for any inconsistencies. Grease compatibility
questions should be referred to your AMSOIL representative
or AMSOIL Inc.
APPLICATION MAINTENANCE
Maintaining a clean work environment is
important when equipment greasing is performed. Wipe grease
fitting clean prior to injecting grease to prevent contaminant
ingestion. Maintain bearing housings one-third to one-half
full of grease. Do not over-grease, as excessive heat buildup
can result. Supplement standard grease maintenance by periodically
cleaning and packing housings with fresh grease on an established
maintenance schedule.
