Shell Omala S2 G 320 oils are formulated using an effective sulphur-phosphorus additive system to provide an extreme pressure performance which allow trouble-free application in most enclosed industrial gearboxes using steel spur and helical gears.

·     Highly loaded gears

Shell Omala S2 G 320 oils have an effective full extreme pressure (EP) additive system allowing them to be used in
highly-loaded gear systems.

·     Other applications

Shell Omala S2 G 320 oils are suitable for lubrication of bearings and other components in circulating and splash-lubricated systems.
For highly loaded worm drives, Shell Omala S4 WE, Shell Morlina S4 B and Shell Omala S1 W are recommended.
For automotive hypoid gears, the appropriate Shell Spirax Oil should be used.
Shell do not recommend/support use in systems with fine filtration (<10 microns) because sustained foam control performance is not assured. Please consult your Shell Local Technical Advisor and Product Application Specialist
