SG Series Synthetic Extreme-Pressure Gear Oil
ISO 68, ISO 100, ISO 150, ISO 220, ISO 320, ISO 460, ISO 680
AMSOIL SG Series Synthetic Gear Oil’s advanced synthetic formulation is fortified with extreme-pressure (EP) additives to provide industrial-grade performance and protection. It is designed to exceed the increased protection needs of gears and bearings operating under severe-service and shock-loading conditions. SG Series Gear Oil delivers complete gearbox protection, with an emphasis on extreme-pressure gear protection, heat resistance and cold-temperature operability.
EXTREME-PRESSURE FORMULATION
SG Series Gear Oil is engineered to prevent metal-to-metal contact and inhibit corrosion. Its shear-stable, high-viscosity-index formulation features excellent anti-foam and air-release properties. SG Series Gear Oil maintains a thick lubricating film and is fortified with a heavy treatment of specialized sulfur/phosphorus EP and anti-corrosion additives. Under extreme pressures that may breach the lubricant film, an iron-sulfide barrier protects gear surfaces and inhibits wear, pitting and scuffing. SG Series Gear Oil demonstrates exceptional extreme-pressure performance in the FZG scuffing and micropitting tests.
HIGH-TEMPERATURE DURABILITY
SG Series Gear Oil is formulated with durable base oils that are naturally resistant to oxidation. It also contains oxidation inhibitors and thermally stable additives for increased resistance to sludge formation, deposits, acid buildup and thermal degradation. AMSOIL SG Series Gear Oil is designed to deliver clean gears and housings throughout a long service life.
EXCELLENT COLD-TEMPERATURE FLUIDITY
SG Series Gear Oil’s high-viscosity-index demonstrates excellent cold-flow properties and extremely low pour points. It helps improve cold-temperature efficiency, reducing the need for sump heaters and seasonal oil changes, while providing easier start-up for equipment.
SG SERIES SYNTHETIC EXTREME-PRESSURE GEAR OIL
- Helps reduce maintenance costs due to excellent extreme-pressure protection
- Promotes long oil and component life by resisting thermal breakdown and water intrusion
- Increases cold-temperature efficiency and protection due to low pour points
- Designed to inhibit wear due to excellent film strength and foam suppression
APPLICATIONS & SPECIFICATIONS
The appropriate viscosity grade of AMSOIL SG Series Synthetic EP Gear Oil is recommended for applications requiring any of the following specifications:
APPLICATION RECOMMENDATION
AMSOIL SG Series Synthetic EP Gear Oil is recommended for industrial gearboxes, including wind-turbine pitch and yaw systems, operating under heavy loads and shock-loading conditions and specifying an extreme-pressure lubricant. This includes, but is not limited to, enclosed industrial spur, bevel, herringbone and helical gears, chain drives and sprockets requiring extreme-pressure additives. It is excellent for use in severe operating conditions and its synthetic properties make it a good all-season lubricant.
Note: AMSOIL SG Series Synthetic EP Gear Oil is not recommended for automotive hypoid gears. It is not recommended for use with yellow metals (copper, brass, bronze) above 100ºC (212ºF) without further testing in the application. AMSOIL SG Series Synthetic EP Gear Oil is not compatible with polyglycol (PAG)-type gear oils. Thorough flushing prior to changeover from polyglycols is required
COMPATIBILITY
AMSOIL SG Series Synthetic EP Gear Oil is compatible with conventional petroleum oils and other synthetic lubricants, including brands popular in wind turbine operations. Contact your wind representative to discuss specific compatibility scenarios.
