Synthetic SG SERIES
Extreme Pressure Gear Oils
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 drain
intervals, and protecting against wear, pitting and rust.
Base
Stock Technology
AMSOIL's SG Oils are compatible with mineral gear oils, synthetic gear
oils*, and sealsmaking 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 utilized 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 anti-foam agents.
The SG Oil's 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 anti-oxidants 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 gear**, 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 poly glycol-type gear oils. Thorough flushing prior to changeover
is required.
** AMSOIL SG Series Gear Oils
are not recommended for use in worm gear or yellow metal containing
applications 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.
