Shell Omala S2 GX 460
Shell Omala S2 GX 460 is a high-quality extreme-pressure (EP) industrial gear oil developed to provide reliable lubrication and extended service life in demanding gear applications. Formulated using carefully selected base oils and advanced additive technology, the lubricant delivers excellent load carrying capacity, strong protection against wear and micropitting, and reliable resistance to oxidation and thermal degradation. These characteristics make Shell Omala S2 GX 460 particularly suitable for enclosed industrial gearboxes operating under heavy loads and severe operating conditions.
One of the key advantages of Shell Omala S2 GX 460 is its ability to provide extended oil life. Industrial gear systems often operate under high mechanical loads and elevated temperatures, which can accelerate lubricant degradation. Shell Omala S2 GX 460 is formulated to resist thermal and chemical breakdown throughout the oil service interval. Its strong oxidation stability helps minimise sludge formation and maintain consistent lubrication performance even when bulk oil temperatures reach up to approximately 100°C. This capability helps reduce maintenance requirements and supports lower total operating costs for industrial equipment.
Shell Omala S2 GX 460 also offers excellent protection against wear and micropitting.The advanced EP additive system forms a protective lubricating film on gear tooth surfaces, reducing metal-to-metal contact and protecting gears and bearings from surface damage. This helps extend the operational life of gearbox components and maintain reliable mechanical performance.
Another important benefit of Shell Omala S2 GX 460 is its ability to maintain efficient gearbox operation. The lubricant demonstrates excellent water separation properties, allowing water contamination to separate easily from the oil so it can be drained from the lubrication system. This helps reduce the risk of corrosion on internal surfaces and minimise the potential for surface fatigue in gears and bearings. In addition, the formulation provides enhanced corrosion protection and improved foam control, ensuring stable lubrication performance even in systems where oil circulation or reservoir residence time may be limited.
Shell Omala S2 GX 460 is recommended for enclosed industrial gear systems using steel-on-steel gear designs such as spur, helical and planetary gear drives. It is suitable for highly loaded gearboxes 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 460 mm²/s at 40°C and 30.8 mm²/s at 100°C with a viscosity index of approximately 97. The oil has a density of approximately 904 kg/m³ at 15°C, a flash point above 250°C and a pour point of approximately –12°C, supporting reliable lubrication performance across a wide range of industrial operating conditions.
