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.
