Shell Omala S2 GX 220 is a high-quality extreme-pressure (EP) gearbox oil primarily designed for heavily loaded industrial gears. The excellent protection against high loads, the excellent protection against micro-pitting and compatibility with elastomers and paint offer superior performance in gears with closed sump.
Main uses of Shell Omala S2 GX 220 are:
Industrial gearboxes with closed sump
Heavily loaded systems with oil lubrication and circulation systems
Non-gear related applications (roller bearings and other (steel on steel) parts with splash or forced circulation systems).
Main Applications
Enclosed industrial gear systems - Shell Omala S2 GX 220 technology provides an effective extreme pressure (EP) formulation designed specifically for enclosed industrial gearboxes using steel-on-steel, spur, helical, or planetary gear drives, including highly loaded systems with a splash or forced circulation systems. Shell Omala S2 GX 220 oils are also suitable for the lubrication of non-geared applications, that include bearings and other steel-on-steel components with a splash or forced circulation systems.
Other applications - Shell offers a wide range of products for other gear ·applications that have their own specific requirements Shell Omala S4 GXV 220 is recommended for gear systems where a synthetic lubricant is specified, when the longest lifespan is required, or when operating in environments that experience large temperature variations.
Shell Omala S2 GX 220 is approved by Siemens AG for use in Flender, helical, bevel, planetary and marine gear units.
Performance, Features & Benefits
Long oil life through oxidation stability and resistance to thermal stress – leading to a reduced total cost of ownership - Shell Omala S2 GX 220 oils are formulated to reduce the risk of thermal and chemical breakdown throughout the maintenance interval. They withstand high thermal loading and resist the formation of sludge to provide extended oil life capability, even with bulk oil temperatures of up to 100C.·
Excellent wear and micropitting protection - Shell Omala S2 GX 220 is formulated to have the excellent load carrying capacity and micropitting performance, providing long component life
Gear system efficiency is maintained by optimized water separation performance, corrosion and foam control - Shell Omala S2 GX 220 oils display a combination of excellent water shedding capability, corrosion protection and low foam forming tendency. Water can greatly accelerate surface fatigue of gears and bearings as well as promoting ferrous corrosion on internal surfaces. Excellent corrosion protection is provided, even in the presence of contamination by seawater and solids. The oils are designed to minimize the potential for foaming, often experienced in applications where oil reservoir residence times are marginal. Excellent shear stability maintains viscosity stability throughout the service interval. Further system efficiencies are gained through compatibility with popular seals, sealants, and engineering adhesives, to help avoid leakage. Shell Omala S2 GX 220 is compatible with prevalent paint finishes.
