Shell Omala S4 GXV 220
Shell Omala S4 GXV 220 is a high-performance synthetic industrial gear oil developed to provide outstanding lubrication in demanding gear applications. Formulated using specially selected synthetic base fluids and advanced additive technology, the lubricant delivers exceptional resistance to wear, strong load carrying capability and superior protection against micropitting. Shell Omala S4 GXV 220 is approved by major gearbox manufacturers including Flender and is designed for use in industrial gear systems operating under severe conditions where reliability and extended oil life are essential.
One of the key advantages of Shell Omala S4 GXV 220 is its ability to provide significantly extended oil service life compared with conventional mineral gear oils. Industrial gearboxes often operate under high loads and varying temperatures that can accelerate lubricant degradation. Shell Omala S4 GXV 220 is formulated with an advanced additive system and synthetic base oils that provide outstanding 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 downtime associated with oil changes.
Shell Omala S4 GXV 220 also offers excellent protection against wear and micropitting. The lubricant’s advanced EP additive technology forms a durable protective film on gear tooth surfaces, reducing metal-to-metal contact and protecting gears and bearings from damage. This enhanced protection helps extend component life and supports reliable operation of gear systems even under shock loading conditions.
Another important benefit of Shell Omala S4 GXV 220 is its contribution to maintaining system efficiency. The synthetic formulation provides improved low-temperature flow characteristics compared with conventional mineral oils, allowing the lubricant to circulate more effectively during start-up conditions. In addition, the lower friction characteristics of synthetic base oils help reduce internal power losses within gear systems, potentially improving energy efficiency while maintaining effective lubrication across a wide temperature range.
Shell Omala S4 GXV 220 is recommended for enclosed industrial reduction gear systems operating under severe operating conditions, including high loads, wide temperature variations and installations where maintenance access may be limited. It is particularly suitable for gear motor systems and other installations requiring extended oil life. The lubricant can also be used for lubricating bearings and other components in splash or circulating lubrication systems.
Physical characteristics include a kinematic viscosity of approximately 220 mm²/s at 40°C and 30 mm²/s at 100°C with a viscosity index of approximately 171. The oil has a density of approximately 864 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.
