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+
(#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.
