PRODUCT DESCRIPTION AMSOIL GH Series Heavy Duty EP grease is composed of synthetic base oils
and lithium-complex thickeners that provides 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 and good low
temperature torque values and pumping capabilities. AMSOIL Heavy Duty EP Grease
is 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.
AMSOIL Heavy Duty EP Grease is formulated with a top performing
lithium complex thickener system that provides excellent water resistance as
identified by the ASTM D-1264 water washout test. AMSOIL Heavy Duty EP Grease
adheres to metal and is shear stable during severe mechanical activity,
maintaining consistency and providing superior lubrication
protection.
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 Heavy Duty EP Grease is
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, 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 Heavy Duty EP Greases
are suitable for use up to 325º F. When operating at elevated temperatures,
frequent regreasing may be required.
AMSOIL Heavy Duty EP 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 AMSOIL Heavy Duty EP 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.
AMSOIL PRODUCT AVAILABILITY AMSOIL GH Series Greases are available in 14-oz. cartridges, 35-lb.
pails, 120-lb. kegs and 400-lb. drums.
AMSOIL Industrial Lubricants are stocked in Superior, Wisconsin
and in select regional distribution centers throughout the United States and
Canada. AMSOIL will stock additional quantities of lubricants or special order
products based on customer requests and regional demands.
