Applications

• Enclosed industrial worm gear systems

Recommended for industrial worm gear reduction systems operating under severe operating conditions, such as high load, very low or elevated temperatures and wide temperature variations.

• Extended life systems

Shell Omala S4 WE is particularly recommended for certain systems where maintenance is infrequent or systems are inaccessible (eg yaw gears in wind turbine installations).

• Other applications

Shell Omala S4 WE oils are suitable for lubrication of bearings and other components in circulating and splash-lubricated systems.

Shell Omala S4 WE is not recommended for the lubrication of components manufactured from aluminium or aluminium alloys.

For highly-loaded spur and helical gears the Shell Omala “G” series oils are recommended.

For automotive hypoid gears, the appropriate Shell Spirax Oil should be used.
