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 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 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.
