    Shell Omala S4 GX – Advance Synthetic Industrial Gear Oils

    Shell Omala S4 GX is an advanced synthetic heavy duty industrial gear oil offering outstanding lubrication performance under severe operating conditions, including reduced friction, long service life and high resistance to micro-pitting for optimal gear protection.

    Perfomance Benefits

    • Long oil life – Maintenance saving 

    Shell Omala S4 GX is formulated using an advanced additive system in combination with specially selected synthetic base fluids to provide outstanding resistance to breakdown over long duration and/or high temperature operation.

    This performance is recognised by Flender AG where a formal approval for 20,000 hours (four years) at 80oC usage as been granted.

    Shell Omala S4 GX can operate successfully at bulk temperatures up to 120oC.

    Shell Omala S4 GX offers the potential to significantly extend service intervals compared to conventional industrial gear oils.

    • Excellent wear & corrosion protection

    Shell Omala S4 GX is formulated to have excellent load carrying capacity and micro-pitting performance providing long component life even under shock loading conditions. These features provide benefits over mineral oil-based products in terms of gear and bearing component life.

    Shell Omala S4 GX also has excellent corrosion protection, even in the presence of contamination by water and solids

    • Maintaining system efficiency

    Shell Omala S4 GX can help maintain or enhancethe efficiency of industrial gear systems through improved low temperature performance and lower friction in comparison to mineral oil-based products. This provides better lubrication at low start-up temperatures

    Shell Omala S4 GX oils have excellent water separation properties, such that excess water can be drained easily from lubrication systems to help extend the life of the gears and ensure efficient lubrication of the contact areas


    • Wind turbines and other inaccessible installations

    Shell Omala S4 GX is particularly recommended for certain systems where extra long life is required, maintenance is infrequent or systems are inaccessible.

    • Enclosed industrial gear systems 

    Recommended for industrial reduction gear systems operating under severe operating conditions, such as high load, very low or elevated temperatures and wide temperature variations

    • Other applications 

    Shell Omala S4 GX oils are suitable for lubrication of bearings and other components in circulating and splash-lubricated systems

    For highly loaded worm drives the Shell Omala “W” series oils are recommended.

    For automotive hypoid gears, the appropriate Shell Spirax Oil should be used
