Description
Shell Omala S2 GX 220 is a high-quality, extreme-pressure (EP) industrial gear oil designed primarily for the lubrication of heavy-duty enclosed gear systems. It is formulated with advanced additives to protect against micropitting and wear while extending component life.
Key Performance Features
- Micropitting Protection: Engineered to resist the specialized form of surface fatigue known as micropitting, which helps extend the life of gears and bearings.
- Excellent Load Carrying: Contains a sulfur-phosphorus additive system that provides high load-carrying capacity for steel-on-steel industrial gears.
- Long Service Life: Resistant to oxidation and thermal stress, preventing the formation of sludge even at bulk oil temperatures up to 100°C.
- System Efficiency: Displays excellent water separation (demulsibility), corrosion protection, and low foaming tendencies to maintain gear system performance.
Applications
- Enclosed Industrial Gears: Suitable for spur, helical, planetary, and marine gear units.
- Highly Loaded Systems: Ideal for gearboxes subject to heavy loads and shock loading.
- Circulating Systems: Can be used in splash-lubricated and forced-circulation systems, as well as for the lubrication of bearings.
