Shell Omala S4 GXV Plus 220
Shell Omala S4 GXV Plus 220 is a high-performance fully synthetic industrial gear oil developed to deliver superior protection, efficiency and long service life in heavily loaded gear systems. Formulated using advanced polyalphaolefin (PAO) synthetic base oil technology combined with carefully selected additive systems, the lubricant is designed to provide exceptional reliability in demanding industrial applications. It is particularly suited for gearboxes operating under high loads, elevated temperatures and challenging operating environments where long lubricant life and dependable protection are essential.
One of the key benefits of Shell Omala S4 GXV Plus 220 is its outstanding protection against micropitting and wear. Modern industrial gear systems can experience extremely high contact pressures that may lead to surface fatigue and micropitting damage. The advanced additive technology used in this formulation helps protect gear teeth from micropitting, scuffing and wear, helping extend gear life and improve overall gearbox reliability. The oil also offers excellent load-carrying capability, achieving an FZG load stage of 14, which demonstrates its ability to protect gears operating under severe mechanical stress.
Shell Omala S4 GXV Plus 220 also delivers excellent thermal and oxidation stability. Industrial gear systems operating at high temperatures can accelerate lubricant degradation, leading to sludge and deposit formation that can affect equipment performance. The advanced synthetic formulation resists oxidation and maintains oil stability at operating temperatures up to approximately 120°C. This helps minimise deposit formation, maintain system cleanliness and ensure reliable lubrication performance throughout extended service intervals.
Another important advantage of Shell Omala S4 GXV Plus 220 is its wide operating temperature capability and improved efficiency. The synthetic base oil provides excellent low-temperature fluidity while maintaining a high viscosity index, allowing the lubricant to maintain stable viscosity across a broad temperature range. This helps ensure reliable lubrication during cold start conditions while maintaining strong oil film protection at high operating temperatures. Improved fluid efficiency can also help reduce energy losses within the gearbox, contributing to improved mechanical efficiency and lower operating costs.
Shell Omala S4 GXV Plus 220 is particularly suitable for use in industrial reduction gear systems operating under severe conditions, including those subject to heavy loads or temperature extremes. It is also widely used in wind turbine gearboxes, where long lubricant life and reliable protection are critical. In addition to gearboxes, the oil can also be used in bearings and circulation lubrication systems where high-performance industrial gear oils are required.
The product meets key industry specifications including ISO 12925-1 Type CKD, DIN 51517-3 (CLP) and ANSI/AGMA 9005-F16. It also carries approvals from leading equipment manufacturers such as Siemens AG for use in Flender gearboxes. With a viscosity grade of ISO VG 220, properties include a density of approximately 864 kg/m³ at 15°C and a pour point of approximately −42°C, supporting reliable performance across a wide range of industrial operating conditions.
