Shell Omala S4 GXV 680
Shell Omala S4 GXV 680 is a high-performance synthetic industrial gear oil designed to deliver outstanding lubrication performance in demanding industrial gear applications. Developed using specially selected synthetic base fluids combined with advanced additive technology, the lubricant provides excellent load carrying capability, superior resistance to micropitting and strong protection against wear. Shell Omala S4 GXV 680 is approved by leading gearbox manufacturers including Flender and is formulated to meet the requirements of modern industrial gear systems operating under severe conditions where reliability and extended service intervals are critical.
One of the key advantages of Shell Omala S4 GXV 680 is its ability to provide significantly extended oil service life compared with conventional mineral gear oils. Industrial gear systems frequently operate under high loads, elevated temperatures and challenging operating environments that can accelerate lubricant degradation. Shell Omala S4 GXV 680 is formulated with an advanced additive system and high-performance synthetic base fluids that offer excellent resistance to oxidation and thermal breakdown. The lubricant can operate effectively at bulk oil temperatures up to approximately 120°C, helping extend maintenance intervals and reduce equipment downtime associated with oil changes.
Shell Omala S4 GXV 680 also delivers 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 under demanding operating conditions or shock loading.
Another important benefit of Shell Omala S4 GXV 680 is its ability to maintain system efficiency. The synthetic formulation provides improved low temperature fluidity compared with mineral oils, allowing the lubricant to circulate more effectively during cold start conditions. In addition, the lower friction characteristics of synthetic base oils help reduce internal power losses within gear systems, supporting efficient operation while maintaining stable lubrication performance across a wide range of operating temperatures.
Shell Omala S4 GXV 680 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 installations where extended oil life and reliable lubrication performance are required. 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 680 mm²/s at 40°C and 74 mm²/s at 100°C with a viscosity index of approximately 191. The oil has a density of approximately 868 kg/m³ at 15°C, a flash point of approximately 240°C and a pour point of approximately –42°C, supporting reliable lubrication performance across a wide range of industrial operating environments.
