Shell Omala S4 WE 460

 

Premium synthetic industrial gear oil

Shell Omala S4 WE is a premium synthetic heavy duty industrial worm gear oil, formulated using polyalkylene glycol base stocks and a specially selected additive system. This provides superior lubrication properties under severe operating conditions, including enhanced energy efficiency, long service life and high resistance to micro-pitting.

Features & Benefits

1. Long oil life - Save maintenance costs

• Shell Omala S4 WE is formulated to provide excellent thermal and oxidation stability, extending oil life and resisting the formation of harmful oxidation products at high operating temperatures.
• This helps maintain system cleanliness and prolong maintenance intervals.
• Shell Omala S4 WE has the ability to significantly extend oil change intervals compared to conventional gear oils.

2. Excellent abrasion resistance

• Shell Omala S4 WE is formulated to have excellent load carrying capacity, helping to extend equipment life even under shock loading conditions.
• The oil is also highly resistant to micropitting, providing benefits in gear and bearing life compared to mineral oils.

3. Maintain system performance

• Shell Omala S4 WE helps improve energy efficiency and reduce operating temperatures in worm drive applications.
• Rig testing shows performance improvements of up to 15% compared to mineral oil-based products and 11% compared to other hydrocarbon-based synthetic oils.
• These results are confirmed through testing by original equipment manufacturers (OEMs) and through practical experience.

Main Applications

1. Closed industrial worm gear systems

• Recommended for industrial worm gear reducers operating under harsh conditions such as heavy loads, very low or very high temperatures, or wide temperature variations.

2. Increase system lifespan

• Shell Omala S4 WE is particularly recommended in systems that require infrequent maintenance or are difficult to access (e.g. vertical shaft turning gears in wind turbines).

3. Other applications

• Shell Omala S4 WE is suitable for lubricating bearings and other equipment in circulating or splash lubrication systems.
• Note: Shell Omala S4 WE is not recommended for the lubrication of components made from aluminum or aluminum alloys.
• For heavily loaded spur and helical gears, the Shell Omala "G" series is recommended.
• For automotive hypoid gears, suitable Shell Spirax oils should be used.

Compatibility & Mixing

1. Compatible with paints & sealing materials

• High quality epoxy paint is recommended, as polyalkylene glycol may damage some conventional paints.
• Shell Omala S4 WE is suitable for nitrile and Viton sealing materials, although Viton is preferred.

2. Oil change procedure

• Shell Omala S4 WE contains polyalkylene glycol and is not compatible with mineral oils or most other synthetic oils.
• Particular care should be taken when changing from other products to Shell Omala S4 WE.
• The system should be flushed with the minimum amount of Shell Omala S4 WE, run at idle and drained while still warm.
• Ideally, seals in contact with mineral oil should be replaced.
• After a few days of use, the lubricating oil should be checked to ensure the system is clean and uncontaminated.
• Shell Omala S4 WE is not miscible with other polyalkylene glycol oils, so special care should be taken when adding the oil.
