    Extreme-Pressure Protection<\/strong><\/p>\n

    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.<\/p>\n

    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 industry-standard Timken OK Load, FZG Scuffing Load and micropitting tests.<\/p>\n

    \n

    High-Temperature Durability<\/strong><\/p>\n

    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.<\/p>\n

    All viscosities of SG Series passed the ISO 12925-1 (CKD) test, demonstrating its high-temperature performance. To achieve the CKD level of oxidation resistance, the oil must pass the ASTM D2893 oxidation test at a temperature of 121\u00baC (250\u00baF) for 312 hours (13 days), after which viscosity increase and precipitants (\u201cfall out\u201d) are measured. SG Series helps deliver clean gears and housings throughout a long service life.<\/p>\n

    \n

    Excellent Cold-Temperature Fluidity<\/strong><\/p>\n

    SG Series Gear Oil\u2019s wax-free, high-viscosity-index base oils demonstrate 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.<\/p>\n

    \n

    APPLICATIONS & SPECIFICATIONS<\/strong><\/p>\n

    The appropriate viscosity grade of AMSOIL SG Series Synthetic EP Gear Oil is recommended for applications requiring any of the following specifications:<\/p>\n

      \n
    • AGMA 9005-E02<\/li>\n
    • US Steel* 224<\/li>\n
    • Cincinnati Machine*<\/li>\n
    • ISO 12925-1 (CKD)<\/li>\n
    • David Brown* S1.53.101 (Type E)<\/li>\n
    • DIN 51517 Part 3<\/li>\n<\/ul>\n

      AMSOIL SG Series Synthetic EP Gear Oil is NOT<\/strong> suitable for the following:<\/p>\n

        \n
      • Automotive hypoid gears<\/li>\n
      • Yellow metals (copper, brass or bronze) above 100\u00baC (212\u00baF)<\/li>\n<\/ul>\n
        \n

        APPLICATION RECOMMENDATION<\/strong><\/p>\n

        AMSOIL SG Series Synthetic EP Gear Oil is recommended for industrial applications operating under heavy loads and shock-loading conditions and specifying an extreme-pressure lubricant.<\/p>\n

        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.<\/p>\n

        Always review the original equipment manufacturer (OEM) requirements and the operating conditions and temperatures to confirm this product\u2019s suitability for your equipment or application.<\/p>\n

        \n

        COMPATIBILITY<\/strong><\/p>\n

        AMSOIL SG Series Synthetic EP Gear Oil is NOT compatible with polyglycol (PAG)-type gear oils.<\/strong> Thoroughly flush prior to changeover.<\/p>\n
