Product Features

Shell Omala S4 WE 220 Synthetic Gear Oil - 20 Litres

Shell Omala S4 WE is an advanced synthetic industrial gear oil designed for heavy-duty worm drive applications. It is formulated with specially selected polyalkylene glycol base fluids and additives to deliver outstanding lubrication performance under severe operating conditions. This oil offers improved energy efficiency, extended service life, and high resistance to micro-pitting, making it ideal for enclosed industrial worm gear systems, extended life systems, and other applications where high load, extreme temperatures, or wide temperature variations are present.

Key features and benefits :
Long Oil Life: Excellent oxidation and thermal stability for extended service intervals and reduced maintenance.
Excellent Wear Protection: High load-carrying capacity and resistance to micro-pitting for long component life.
Maintaining System Efficiency: Improved energy efficiency and lower operating temperatures in worm gear applications.

Shell Omala S4 WE is recommended for enclosed industrial worm gear systems operating under severe conditions, such as high loads, extreme temperatures, and wide temperature variations. It is also particularly well-suited for extended life systems where maintenance is infrequent or difficult to access, such as yaw gears in wind turbine installations. Additionally, it can be used for the lubrication of bearings and other components in circulating and splash-lubricated systems. However, it is not recommended for components made from aluminum or aluminum alloys.
