Shell Omala S4 GX 220

1 Technical Data SheetPrevious Name: Shell Omala HDShell Omala S4 GX 220 Extra Life and Protection Special Applications Advanced Synthetic Industrial Gear OilShell Omala S4 GX is an advanced synthetic heavy duty industrial gear oil offering outstanding lubricationperformance under severe operating conditions, including reduced friction, long service life and high resistance tomicro-pitting for optimal gear , Features & BenefitsLong oil life - maintenance saving Shell Omala S4 GX is formulated using an advancedadditive system in combination with specially selectedsynthetic base fluids to provide outstanding resistance tobreakdown over long duration and/or high Omala S4 GX can operate successfully at bulktemperatures up to Omala S4 GX offers the potential to significantlyextend service intervals compared to conventionalindustrial gear wear and corrosion protection Shell Omala S4 GX is formulated to have excellent loadcarrying capacity and micro-pitting performance

2 Providinglong component life even under shock loading features provide benefits over mineral oil-basedproducts in terms of gear and bearing component Omala S4 GX also has excellent corrosion protection,even in the presence of contamination by water and system efficiency Shell Omala S4 GX can help maintain or enhance theefficiency of industrial gear systems through improved lowtemperature performance and lower friction in comparisonto mineral oil-based products. This provides betterlubrication at low start-up ApplicationsWind turbines and other inaccessible installations Shell Omala S4 GX is particularly recommended for certainsystems where extra long life is required, maintenance isinfrequent or systems are industrial gear systems Recommended for industrial reduction gear systemsoperating under severe operating conditions, such as highload.

3 Very low or elevated temperatures and widetemperature applications Shell Omala S4 GX oils are suitable for lubrication ofbearings and other components in circulating and splash-lubricated geared systems, or other applications that employ afiltration unit finer than 5 microns, please consult your ShellLocal Technical Advisor and Product Application Specialistbefore using Shell Omala S4 highly loaded worm drives the Shell Omala W seriesoils are recommended. For automotive hypoid gears, theappropriate Shell Spirax Oil should be 1 of 3 Omala S4 GX 220, v Typical Physical Characteristics These characteristics are typical of current production.
