Shell Omala S4 WE 680

Shell Omala S4 WE 680 Main 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 680 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 680 oils are suitable for lubrication of bearings and other components in circulating and splash- lubricated systems. Shell Omala S4 WE 680 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.

Performance, Features & Benefits of Shell Omala S4 WE 680

+ Long oil life - maintenance saving

Shell Omala S4 WE 680 is formulated to provide excellent oxidation and thermal stability, extending lubricant life and resisting the formation of harmful oxidation products at high operating temperatures. This helps maintain system cleanliness over extended maintenance intervals. Shell Omala S4 WE 680 offers the potential to extend service intervals significantly compared to conventional industrial gear oils.

+ Excellent wear protection

Shell Omala S4 WE 680 is formulated to have excellent load carrying capacity providing long component life even under shock loading conditions. It also has a high resistance to micro-pitting. These features provide benefits over mineral oil-based products in terms of gear and bearing component life.

+ Maintaining system efficiency"

Shell Omala S4 WE 680 offers improved energy efficiency and lower operating temperatures in worm gear applications. Rig testing has shown efficiency improvements of up to 15% in comparison with mineral oil-based products and 11% over other synthetic hydrocarbon-based lubricants. These results have been confirmed by OEM testing and field experience.

Compatibility & Miscibility

Seal & Paint Compatibility

Seal & Paint Compatibility High-quality epoxy paints are recommended, as polyalkylene glycols will tend to attack certain conventional paints. Shell Omala S4 WE 680 has been found to be satisfactory with nitrile and Viton seal materials, although Viton seals are preferred.

Change-over Procedure

Shell Omala S4 WE 680 contains polyalkylene glycols and is not compatible with mineral oils or most other synthetic lubricant types. Care should be taken when changing from such products to Shell Omala S4 WE 680. The system should be flushed with the minimum quantity of Shell Omala S4 WE 680, operating under no load and draining whilst warm. Ideally, seals exposed to mineral oils should also be replaced. Inspect the lubricant after a few days use. Ensure that oil systems are clean and free from contamination. Shell Omala S4 WE 680 is also not miscible with some other polyalkylene glycols, so caution is needed when topping-up. Generally, the preference is to avoid mixtures by draining and refilling.
