Shell Omala S2 GX 150
Shell Omala S2 GX 150 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 excellent load carrying capacity, strong protection against wear and micropitting, and dependable resistance to oxidation and thermal stress. These properties make Shell Omala S2 GX 150 particularly suitable for enclosed industrial gear systems operating under heavy loads and challenging operating conditions.
One of the key advantages of Shell Omala S2 GX 150 is its ability to provide extended oil life. Industrial gear systems can operate under significant mechanical stress and elevated temperatures, which can accelerate lubricant degradation. Shell Omala S2 GX 150 is formulated to resist thermal and chemical breakdown throughout the oil service interval. Its strong oxidation stability helps prevent sludge formation and maintains consistent lubrication performance even when bulk oil temperatures reach approximately 100°C. This stability helps reduce maintenance requirements and contributes to lower overall operating costs.
Shell Omala S2 GX 150 also provides excellent wear protection and resistance to micropitting. The advanced EP additive system forms a durable protective film on gear tooth surfaces, reducing metal-to-metal contact and protecting components from surface damage. This helps extend the operational life of gears, bearings and other gearbox components.
Another important benefit of Shell Omala S2 GX 150 is its ability to maintain efficient and reliable gearbox operation. The lubricant provides excellent water separation properties, allowing water contamination to separate easily from the oil so that it can be removed from the lubrication system. This helps reduce the risk of corrosion on internal components and minimises the potential for surface fatigue in gears and bearings. The formulation also delivers improved corrosion protection and excellent foam control, ensuring consistent lubrication performance even in systems where oil circulation or reservoir residence time may be limited.
Shell Omala S2 GX 150 is recommended for enclosed industrial gearboxes using steel-on-steel gear designs such as spur, helical and planetary gear drives. It is suitable for heavily loaded gear systems operating with either splash lubrication 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 150 mm²/s at 40°C and 15 mm²/s at 100°C with a viscosity index of approximately 98. The lubricant has a density of approximately 897 kg/m³ at 15°C, a flash point above 240°C and a pour point of approximately –24°C, supporting reliable lubrication performance across a wide range of industrial operating conditions.
