Shell Omala S4 WE

Synthetic oils based on polyglycols with very good low-temperature characteristics, thermal and oxidative stability and anti-friction properties. Designed for high-speed / high-loaded gearboxes, especially worm gears (steel-bronze steam), as well as circulating bearing lubrication systems (for example, paper machine calenders).

Not recommended for aluminum-containing bronze alloys.

Specifications: [David Brown S1.53.105 G, ISO 12925-1 type СКЕ, ANSI/AGMA 9005-EO2 (EP)], Flender AG, Bonfiglioli.

Shell Omala S4 GX

Synthetic industrial oils with exceptionally high performance. Used for the lubrication of bearings and closed gears under the most severe operating conditions and at high loads. Recommended for industrial gearboxes operating at constant high temperatures, and for some systems (gearboxes or bearings), designed for long intervals between oil changes or without oil change (“lifetime” lubrication).

Specifications: [ ISO 12925-1 CKD, DIN 51517-3 CLP HC, ANSI/AGMA 9005-ЕО2 (ЕР), US Steel 224, David Brown S1.53.106], Flender AG, approved for wind turbine gearboxes: Gamesa, Dongfang Wind Turbines, Dalian Heavy Industries, Sinovel.

Shell Omala S2 G

Mineral oils for heavily loaded gears, bearings. The additive composition provides high anti-seize and anti-corrosion properties. Maintain high bearing capacity in steel gears. Oils can be used in oil mist lubrication systems.

Shell Omala S1 W 460

Refined, highly viscous mineral oil, compounded with a small amount of fatty oils. It is mainly used for lubrication of steam engine cylinders operating at high temperatures and pressures, when low carbonization and “steaming” are important factors.

Specifications : AGMA 9005-EO2 (CP).

Shell Omala

High quality industrial gear and bearing oils

Shell Omala is a high-quality, lead-free, high-pressure, anti-seize oil designed to lubricate heavy duty industrial gears. High bearing capacity and antifriction characteristics allow the successful use of these oils in gears and other applications.

Area of usage

Shell Omala oils, developed on the basis of highly refined base oils with a high viscosity index and compositions of special sulfur-phosphorus additives to impart extreme pressure properties, can be successfully used in the following areas:

  • Steel Gear Transmissions
  • Industrial gears requiring anti-seize oils
  • Bearings
  • Circulation and spray lubrication systems

Shell Omala oils cannot be used in automotive hypoid gears. They recommend the use of Shell Spirax family oils.


  • Excellent oxidation and heat resistance

Resist thermal stress, deposits and other harmful oxidation products. Long service life, even at oil temperatures up to 100 ° C in some applications.

  • Effective Corrosion Inhibitors

Protect both steel and bronze parts, even in the presence of water and particulate matter.

  • Lead free

Less hazardous to personnel health and disposal.

  • Wide viscosity range

Oils for the most diverse and most critical nodes.

  • Demulsifying properties

Shell Omala oils exhibit high demulsifying properties, so water can be easily removed from the lubrication system. (Water can significantly increase the surface fatigue of gears and bearings, as well as cause corrosion on the internal surfaces of parts. This is why water should not be allowed to enter the oil or should be removed immediately from the system).

  • Excellent load bearing capacity

Reduced wear of teeth and bearings, steel and bronze. Laboratory tests show that the load-bearing capacity of Shell Omala oils is significantly higher than that of gear oils containing lead. Tooth wear is significantly reduced, in particular at high loads. Typical Results for Shell Omala 220:
