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.
