Shell Omala S4 GXV 320
Shell Omala S4 GXV 320 is a high-performance synthetic industrial gear oil developed to provide outstanding lubrication performance in demanding industrial gear applications. Formulated using specially selected synthetic base fluids combined with advanced additive technology, the lubricant offers excellent load carrying capability, high resistance to micropitting and superior protection against wear. The product is approved by major gearbox manufacturers including Flender and is designed to perform reliably in modern gear systems operating under severe conditions where extended oil life and equipment protection are essential.
One of the key advantages of Shell Omala S4 GXV 320 is its ability to deliver significantly extended service life compared with conventional mineral gear oils. Industrial gear systems often operate under high loads, elevated temperatures and demanding operating environments that can accelerate lubricant degradation. Shell Omala S4 GXV 320 is formulated with an advanced additive system and high-performance synthetic base fluids that provide excellent resistance to oxidation and thermal breakdown. The lubricant can operate effectively at bulk oil temperatures of up to approximately 120°C, helping to extend maintenance intervals and reduce equipment downtime associated with oil changes.
Shell Omala S4 GXV 320 also offers excellent wear protection and strong resistance to micropitting. The advanced EP additive system forms a durable lubricating film between contacting metal surfaces, reducing friction and protecting gears and bearings from wear. This improved protection helps extend component life and maintain reliable operation even in systems subject to shock loading or demanding mechanical stress.
Another important benefit of Shell Omala S4 GXV 320 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 easily during cold start conditions. At the same time, the lower friction characteristics of the synthetic base oil can help reduce energy losses within gear systems, supporting efficient operation and stable lubrication performance across a wide range of operating temperatures.
Shell Omala S4 GXV 320 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 equipment where long oil life and reliable 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 320 mm²/s at 40°C and 37 mm²/s at 100°C with a viscosity index of approximately 169. The oil has a density of approximately 866 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.
