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.
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
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+ (#1 and #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
* Applicable only to NLGI Consistency Grades
#1 and #2
APPLICATION RECOMMENDATION
AMSOIL GL Greases grades #0, #1 and #2, are recommended for use
in manual or automatic lubricating systems. NLGI #0 (GLA) and #1
(GLB) have better mobility and are the preferred choice for colder
applications, for automatic lubrication systems with long pumping
runs, and for gear box applications (where recommended by manufacturer).
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.
