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.
