Shell Omala S4 GXV 68
Shell Omala S4 GXV 68 is a high-performance synthetic industrial gear oil developed to provide exceptional lubrication performance in demanding industrial gear applications. Formulated with specially selected synthetic base fluids and advanced additive technology, the lubricant delivers excellent load carrying capability, strong resistance to micropitting and outstanding protection against wear. These properties make Shell Omala S4 GXV 68 particularly suitable for enclosed industrial gear systems operating under severe conditions where long oil life and reliable component protection are essential.
One of the key advantages of Shell Omala S4 GXV 68 is its ability to provide significantly extended oil service life compared with conventional mineral gear oils. Industrial gearboxes frequently operate under high mechanical loads and elevated temperatures that can accelerate lubricant degradation. Shell Omala S4 GXV 68 is formulated using an advanced additive system combined with high-performance synthetic base fluids to provide excellent resistance to oxidation and thermal breakdown. The lubricant can operate effectively at bulk oil temperatures up to approximately 120°C, supporting extended maintenance intervals and reducing downtime associated with oil changes.
Shell Omala S4 GXV 68 also offers excellent protection against wear and micropitting. The lubricant’s advanced EP additive system forms a durable protective lubricating film on gear tooth surfaces, reducing friction and protecting gears and bearings from metal-to-metal contact. This enhanced protection helps extend component life and maintain reliable gearbox performance even in applications subject to heavy loads or shock conditions.
Another important benefit of Shell Omala S4 GXV 68 is its ability to help maintain system efficiency. The synthetic formulation provides improved low temperature fluidity compared with conventional mineral oils, allowing the lubricant to circulate more effectively during cold start conditions. In addition, the lower friction characteristics of synthetic base oils can help reduce internal power losses within gear systems, potentially improving energy efficiency while maintaining effective lubrication across a wide range of operating temperatures.
Shell Omala S4 GXV 68 is recommended for enclosed industrial reduction gear systems operating under severe conditions such as high loads, wide temperature variations and installations where maintenance access may be limited. It is particularly suitable for gear motor systems and other applications where extended oil life and reliable lubrication performance are critical. The lubricant can also be used for lubricating bearings and other components operating in splash or circulating lubrication systems.
Physical characteristics include a kinematic viscosity of approximately 68 mm²/s at 40°C and 11 mm²/s at 100°C with a viscosity index of approximately 157. The oil has a density of approximately 860 kg/m³ at 15°C, a flash point of approximately 240°C and a pour point of approximately –51°C, supporting reliable lubrication performance across a wide range of industrial operating environments.
