Shell Omala S2 GX 68
Shell Omala S2 GX 68 is a high-quality extreme-pressure (EP) industrial gear oil developed to deliver reliable lubrication and long service life in demanding industrial gear applications. Formulated 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 features make Shell Omala S2 GX 68 particularly suitable for enclosed industrial gear systems operating under heavy loads and challenging conditions.
One of the key advantages of Shell Omala S2 GX 68 is its ability to provide extended oil life. Industrial gear systems frequently operate under elevated temperatures and heavy mechanical stress, which can accelerate lubricant breakdown. Shell Omala S2 GX 68 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 reach approximately 100°C. This capability supports longer oil service intervals, helping to reduce maintenance requirements and overall operating costs.
Shell Omala S2 GX 68 also provides excellent protection against wear and micropitting. The advanced EP additive system forms a durable 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 68 is its ability to maintain efficient gearbox operation. The lubricant offers excellent water shedding properties, allowing water contamination to separate easily from the oil so it can be removed 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 circulation or reservoir residence time may be limited.
Shell Omala S2 GX 68 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 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 68 mm²/s at 40°C and 8.7 mm²/s at 100°C with a viscosity index of approximately 100. The lubricant has a density of approximately 885 kg/m³ at 15°C, a flash point above 230°C and a pour point of approximately –24°C, supporting reliable lubrication performance across a wide range of industrial operating environments.
