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.
PERFORMANCE FEATURES
- High dropping point of 500°F+
(#1 and #2)
- Resists thermal and oxidation degradation
(lasts longer than conventional grease)
- Excellent water-washout resistance
- Good low temperature pumpability
and torque values
- Adhesive and shear stable to prevent
squeeze out
* Applicable only to NLGI Consistency
Grades #1 and #2
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.
