Shell Omala S2 GX 100
Shell Omala S2 GX 100 is a high-quality extreme-pressure (EP) industrial gear oil developed to provide reliable lubrication and long service life in demanding gear applications. Formulated using high-performance base oils and advanced additive technology, the lubricant delivers strong load carrying capability, excellent protection against wear and micropitting, and reliable resistance to oxidation and thermal stress. These characteristics make Shell Omala S2 GX 100 particularly suitable for enclosed industrial gear systems operating under heavy loads and challenging conditions.
One of the key benefits of Shell Omala S2 GX 100 is its ability to deliver extended oil life. Industrial gear systems often operate under high temperatures and heavy mechanical loads, which can cause conventional lubricants to degrade over time. Shell Omala S2 GX 100 is formulated to resist thermal and chemical breakdown, helping to minimise sludge formation and maintain consistent lubrication performance throughout the oil service interval. This improved oxidation stability allows the lubricant to perform effectively even when bulk oil temperatures reach up to approximately 100°C, helping reduce maintenance requirements and overall operating costs.
Shell Omala S2 GX 100 also provides excellent wear protection and strong resistance to micropitting. The advanced EP additive system helps form a protective film on gear tooth surfaces, reducing metal-to-metal contact and protecting components from wear and surface fatigue. This helps extend the operational life of gears, bearings and other critical components within the gearbox.
Another important advantage of Shell Omala S2 GX 100 is its ability to maintain system efficiency and cleanliness. The lubricant has excellent water shedding properties, allowing water contamination to separate easily from the oil so that it can be drained from the lubrication system. This helps prevent corrosion of internal components and reduces the risk of surface fatigue in gears and bearings. The formulation also provides improved corrosion protection and excellent foam control, ensuring consistent lubrication performance even in systems where oil residence time may be limited.
Shell Omala S2 GX 100 is recommended for enclosed industrial gearboxes using steel-on-steel gear designs such as spur, helical and planetary gear drives. It is suitable for highly loaded systems operating with splash or forced circulation lubrication methods. In addition to gear systems, the oil can also be used for lubricating bearings and other steel-on-steel components operating under similar lubrication conditions.
Physical characteristics include a kinematic viscosity of approximately 100 mm²/s at 40°C and 11.4 mm²/s at 100°C with a viscosity index of approximately 99. The lubricant has a density of approximately 891 kg/m³ at 15°C, a flash point above 230°C and a pour point of approximately –24°C, supporting dependable lubrication performance across a wide range of industrial operating conditions.
