PRODUCT DESCRIPTION
AMSOIL SG Series Extreme Pressure Gear Oils are made from
shear-stable, high-quality synthetic base oils and are fortified
with additives that deliver high performance in industrial gear
applications. These oils are designed to reduce maintenance costs by
extending equipment life, extending drain intervals, and protecting
against wear, pitting and rust.
Base Stock Technology
AMSOIL SG Oils are compatible with mineral gear oils, synthetic gear
oils*, and seals—making them easy to use. They preserve new seals,
prevent leaks, and help rejuvenate old, brittle seals.
AMSOIL SG synthetic base stocks are inherently
resistant to oxidation, helping provide long life. The naturally
high viscosity indices, low pour points, and lack of paraffins (wax)
make these lubricants ideal for use in wide operating temperature
ranges. At low operating temperatures, equipment starts easier, is
not starved of lubrication from channeling and product
solidification, and the need for sump heaters is reduced. At higher
operating temperatures, AMSOIL SG base oils resist the degradative
effects of oxidation that cause poor lubricant performance, and they
maintain an optimal lubricating film between parts.
The base oils are also hydrolytically stable
and they readily separate from water. This prevents unwanted
oil/water emulsions that have poor lubricating properties, and it
eases water removal from the sump.
Additive Performance
AMSOIL SG Oils are fully formulated with sulphur/phosphorous extreme
pressure additives, antioxidants, rust inhibitors, and antifoam
agents. The thermally stable, extreme-pressure additive system forms
a hard, iron-sulfide coating on metal components. This iron-sulfide
coating prevents metal-to-metal contact under boundary lubrication
conditions, reduces friction and protects components against shock
loading and wear. The antioxidants increase the oxidation resistance
of the synthetic base oils for long, clean lubricant performance.
These oils protect against rust from water or process contaminants
and prevent foaming, ensuring proper lubrication.

APPLICATION RECOMMENDATION
AMSOIL Synthetic SG Series Extreme Pressure Gear Oils are
recommended for industrial applications operating under heavy loads
and shock conditions and specifying an extreme-pressure lubricant.
This includes, but is not limited to, enclosed industrial spur,
bevel, herringbone, helical and worm gears**, chain drives,
sprockets and most metal-on-metal systems requiring extreme-pressure
additives.
These lubricants are excellent for
use in severe operating conditions and their synthetic properties
make them good all-season lubricants.
The SG Series Gear Oils meet the AGMA
ratings for synthetic gear oils and EP gear oils and are recommended
for use in applications specifying these standards. Although AMSOIL
SG Series Oils are compatible with mineral oil based lubricants, for
optimum performance it is recommended that the system be thoroughly
drained and, if warranted, cleaned.
The ability of AMSOIL SG Series Gear
Oils to extend drain intervals is subject to operating conditions
and maintenance practices. Monitoring by oil analysis is
recommended.
NOTES:
*AMSOIL SG Series Gear Oils, as well
as other synthetic or mineral based oils, are not compatible with
polyglycol-type gear oils. Thorough flushing prior to changeover is
required.
**AMSOIL SG Series Gear Oils are not
recommended for use in worm gear applications or applications
containing yellow metal and operating at or above 200°F (93°C). Also
not recommended for use in other applications operating at or above
250°F (171°C). For such applications, please consult your AMSOIL
Dealer or AMSOIL INC.
AMSOIL SG Gear Oils are not
recommended for automotive hypoid gear applications.
AMSOIL PRODUCT WARRANTY
AMSOIL industrial lubricants are formulated to meet or exceed
accepted industry specifications. AMSOIL warrants that the use of
its lubricants will not cause mechanical damage to any mechanically
sound equipment when AMSOIL products are used in full compliance
with the company’s recommendations. However, the purchaser of these
lubricants is responsible for determining if these specifications
are adequate and proper for the intended application. The AMSOIL
warranty is limited to lubricant performance consistent with
indicated specifications. No additional warranty, expressed or
implied, can be made.
AMSOIL PRODUCT AVAILABILITY
AMSOIL products are available in 5-gallon pails, 55- gallon drums,
275-gallon totes and bulk quantities. For 275- gallon totes, please
allow two to four weeks for delivery. 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.
