Synthetic Multi-Purpose Grease
NLGI #0, #1 and #2 (Lithium Complex
- Moly Fortified)
Reduces friction and wear in high-speed,
high-temperature components such as automotive wheel bearings
and electric motors. Keeps components running clean and
trouble free for outstanding performance and long-life.
NLGI #0 and NLGI #1 greases have better mobility and are
preferred for cold temperature and automatic pump systems.
NLGI #2 is the primary wheel bearing recommendation.
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.
AMSOILs 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.
