PRODUCT DESCRIPTION
AMSOIL GLC multi-purpose, EP grease is
qualified against the highest grease standards, NLGI GC
(wheel bearing) and LB (chassis), and is designed for
multiple use applications. This grease is 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. GLC
Grease is 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 GLC Grease adheres
to metal in all types of environments and resists squeeze
out during operation. These qualities ensure maximum
lubricant protection during harsh operations.
AMSOIL GLC multi-purpose greases is
recommended for many different applications. Its diversity
simplifies lubricant inventories and prevents greasing
errors while providing problem-free operation. AMSOIL GLC
Grease reduces repair and maintenance costs.
PERFORMANCE FEATURES
- High dropping point of 550°F
- 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
APPLICATION
RECOMMENDATION
AMSOIL GLC Greases grade #2 is
recommended for use in manual or automatic lubricating
systems. 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.
