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+ (#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
APPLICATION RECOMMENDATION
AMSOIL GL Greases grades #2, are 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.
