Performance, Features & 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 Siemens MD where a formal approval for 20,000 hours (four years) at 80°C usage as been granted.
  
  Shell Omala S4 GX can operate successfully at bulk temperatures up to 120°C.
  
  Shell Omala S4 GX offers the potential to significantly extend service intervals compared to conventional industrial gear oils.
   
• Excellent wear and 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 enhance the 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.

Main Applications

• 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 geared systems, or other applications that employ a filtration unit finer than 5 microns, please consult your Shell Local Technical Advisor and Product Application Specialist before using Shell Omala S4 GX.
  
  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.
