Shell Omala S4 GXV 460
Shell Omala S4 GXV 460 is a high-performance synthetic industrial gear oil designed to provide exceptional lubrication performance in demanding industrial gear applications. Formulated using carefully selected synthetic base fluids combined with advanced additive technology, the lubricant offers excellent load carrying capability, strong 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 long oil life and dependable protection are critical.
One of the key advantages of Shell Omala S4 GXV 460 is its ability to deliver significantly extended oil service life compared with conventional mineral gear oils. Industrial gear systems frequently operate under high mechanical loads, elevated temperatures and demanding operating environments that can accelerate lubricant breakdown. Shell Omala S4 GXV 460 is formulated with an advanced additive system and high-quality synthetic base oils that provide outstanding resistance to oxidation and thermal degradation. The lubricant can operate effectively at bulk oil temperatures up to approximately 120°C, helping to extend maintenance intervals and reduce downtime associated with oil changes.
Shell Omala S4 GXV 460 also provides excellent wear protection and resistance to micropitting. The lubricant’s advanced EP additive system forms a durable lubricating film between contacting metal surfaces, reducing friction and protecting gears and bearings from wear. This enhanced protection helps extend component life and maintain reliable operation even in systems subjected to shock loading or demanding mechanical stresses.
Another important benefit of Shell Omala S4 GXV 460 is its contribution to maintaining 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 can help reduce energy losses within gear systems, supporting efficient operation while maintaining consistent lubrication performance across a wide operating temperature range.
Shell Omala S4 GXV 460 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 where extended oil life is 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 460 mm²/s at 40°C and 53 mm²/s at 100°C with a viscosity index of approximately 179. 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 conditions.
