Category:

Shell Omala S2 G 150

( Previously named: Shell Omala Oils )

Extreme-pressure gear oil for industrial enclosed gear systems

  • Sulphur-phosphorus EP additive system for high load-carrying performance

  • Resists thermal and chemical breakdown under heavy operating conditions

  • Maintains lubrication integrity at bulk temperatures up to 100 °C

  • Excellent gear tooth and bearing wear protection

  • Protects steel components from corrosion even in the presence of water and solids

  • Exceptional demulsibility for easy water drainage from systems

  • Not recommended for filters finer than 10 microns

  • Suitable for steel spur and helical gears in enclosed gearboxes

  • Also used for bearings and splash/circulating-lubricated systems

  • Not for worm gears or hypoid gears—use Shell Omala S4 WE or Spirax oils instead

  • Previously known as Shell Omala Oils

Global Product Code: 001D7836



Application:

Shell Omala S2 G 150 is designed for use in industrial gear systems, particularly enclosed steel gearboxes operating under high loads. It is formulated with a sulphur-phosphorus EP additive system and offers exceptional wear protection, water separation, and thermal stability. This product was previously known as Shell Omala Oils.

Performance Features & Benefits:

  • Extended Oil Life: Resists sludge formation and oxidation even at bulk oil temperatures up to 100 °C, supporting longer maintenance intervals.
  • Wear and Corrosion Protection: Excellent load-carrying capacity reduces gear and bearing wear; protects against rust even with contamination.
  • Water Separation: Demulsifies effectively, enabling quick drainage of water to reduce corrosion and extend gear life.

Main Application Areas:

  • Enclosed industrial gearboxes using spur and helical steel gears
  • Circulating and splash-lubricated bearing systems
  • Not suitable for worm drives or hypoid gears

Specifications & Approvals:

  • Fives Cincinnati P-77
  • AGMA EP 9005-E02
  • ISO 12925-1 Type CKD
  • DIN 51517 Part 3 (CLP)

Environmental & Safety Information:

  • Use impervious gloves when handling used oil; wash skin thoroughly after contact.
  • Do not discharge used oil into drains, soil, or water—return to authorized collection point.
  • Safety Data Sheet (SDS) available via inquiry
