PRODUCT DESCRIPTION AMSOIL
GH Series Extreme Pressure greases are qualified against the highest grease standard,
NLGI GC (wheel bearing) and LB (chassis), and are designed for heavy duty applications.
These greases are composed of synthetic base oils and lithium-complex thickeners
that provide the film strength, shear resistance, and mechanical stability critical
to high load protection. 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 GH Greases are compounded with oxidation and corrosion inhibitors, effective
oil soluble EP additives and molybdenum disulfide (moly) solid EP additives for
all around protection in severe conditions.
The presence of moly provides
an extra measure of protection in shock loading situations common in both construction
and agricultural use. During heavy shock loading, the lubricant film between metal
surfaces can be temporarily ruptured, but moly remains intact to prevent metal
to metal contact which could cause equipment damage. Moly also assists in dirty
environments or when proper re-greasing intervals are not followed. AMSOIL's
top performing lithium complex thickener system provides excellent water resistance
as identified by the ASTM D-1264 water washout test. Therefore, even in wet conditions
a lubricant film remains present to protect equipment against wear while the corrosion
inhibitors prevent rust. AMSOIL GH greases adhere to metal and are shear stable
during severe mechanical activity. These features mean the grease does not thin
during operation, but rather it maintains its consistency and stays in place to
provide good lubrication. PERFORMANCE FEATURES
- Moly Fortified for added EP protection
- Adhesive and Shear Stable -
prevents squeeze out
- High dropping point (exceeds 500ºF)
- Excellent
water-washout resistance
- Oxidation and corrosion inhibited
APPLICATION
RECOMMENDATION AMSOIL GH Greases in grades #1 and #2 are recommended
for use in manual or automatic lubricating systems. NLGI #1 (GHB) greases 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 (GHD) is the preferred choice for medium
to high ambient temperatures, sleeve type bushings, high shock loading environments,
high water environments, and is the primary choice for wheel bearings. The
correct consistency grade of AMSOIL GH EP Moly 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, gears, bushings, thrust
bearings, wheel bearings, chassis lubrication, universal joints, ball joints,
tie-rod ends, steering knuckles, and heavily loaded pivot pins on mining and off
road equipment such as power shovels, draglines, wheel and back hoe loaders, excavators
and bulldozers. AMSOIL GH greases are suitable for use up to 325º F. When operating
at elevated temperatures, frequent regreasing may be required. AMSOIL GH
Lithium Complex Greases are compatible with many other types of grease. 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.
Any 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 fittings 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.
