Shell Omala S2 GX 320
Shell Omala S2 GX 320 is a high-quality extreme-pressure (EP) industrial gear oil developed to deliver reliable lubrication and extended service life in demanding gear applications. Manufactured using carefully selected base oils and advanced additive technology, the lubricant provides excellent load carrying capability, strong resistance to wear and micropitting, and dependable protection against oxidation and thermal degradation. These characteristics make Shell Omala S2 GX 320 particularly suitable for enclosed industrial gearboxes operating under heavy loads and challenging operating conditions.
One of the key advantages of Shell Omala S2 GX 320 is its extended oil life capability. Industrial gear systems often operate under high mechanical loads and elevated temperatures that can accelerate lubricant breakdown. Shell Omala S2 GX 320 is formulated to resist thermal and chemical degradation throughout the maintenance interval. Its strong oxidation stability helps prevent sludge formation and maintains consistent lubrication performance even when bulk oil temperatures approach approximately 100°C. This improved stability supports longer oil drain intervals, reducing maintenance requirements and lowering overall operating costs.
Shell Omala S2 GX 320 also provides excellent wear protection and strong resistance to 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 320 is its ability to maintain efficient gearbox operation. The lubricant demonstrates 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 reduce the risk of corrosion and 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 residence time may be limited.
Shell Omala S2 GX 320 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 systems operating with splash lubrication or forced circulation lubrication methods. 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 320 mm²/s at 40°C and 25 mm²/s at 100°C with a viscosity index of approximately 98. The lubricant has a density of approximately 903 kg/m³ at 15°C, a flash point above 250°C and a pour point of approximately –15°C, supporting reliable lubrication performance across a wide range of industrial operating environments.
