Shell Omala S4 GXV Plus is an advanced full synthetic heavy duty industrial gear oil, approved by both SEW and. Flender, offering outstanding lubrication performance under severe operating conditions, including reduced friction, enhanced energy efficiency, long service life, high resistance to micro-pitting for optimal gear protection and superb compatibility with seals under extreme dynamic conditions.
Applications
Gear motor systems and other inaccessible installationsShell Omala S4 GXV Plus is particularly recommended for certain systems where extra long life is required, maintenance is infrequent or systems are inaccessible. Additionally Shell Omala S4 GXV Plus is recommended for systems where seal leakages are critical for the operation.
Enclosed industrial gear systemsShell Omala S4 GXV Plus is recommended for industrial reduction gear systems operating under severe operating conditions, such as high load, very low or elevated temperatures and wide temperature variations.
Other applicationsShell Omala S4 GXV Plus is suitable for lubrication of bearings and other components in circulating and splash- lubricated systems. For highly loaded worm drives the Shell Omala “W” series oils are recommended. For automotive hypoid gears, the appropriate Shell Spirax Oil should be used.
Performance & benefits
Shell Omala S4 GXV Plus is formulated using an advanced additive system in combination with specially selected synthetic base fluids (mPAO) to provide outstanding resistance to breakdown over long duration and help to reduce deposit formation, sustain film thickness even at higher operating temperatures. Shell Omala S4 GXV Plus can operate successfully at bulk temperatures up to 120 0 C.
Shell Omala S4 GXV Plus offers the potential to significantly extend service intervals due to its excellent thermal and oxidative stability compared to other synthetic oils and esp. mineral industrial gear oils.
Shell Omala S4 GXV Plus is formulated to have high load carrying capacity to resist against scuffing wear and high mircopitting resistance providing long component life even under shock loading conditions. These features provide benefits over mineral oil-based products in terms of gear and bearing component life. Shell Omala S4 GXV Plus also has excellent rust and corrosion protection, even in the presence of contamination by water and solids.
Shell Omala S4 GXV Plus has passed the severe bearing tests and showed no occurrence of WEC damages. So Shell Omala S4 GXV Plus does not promote WEC bearing failures acc. to the FVA 707 workgroup test protocol. Shell Omala S4 GXV Plus can help maintain or enhance the efficiency of industrial gear systems through improved low temperature performance and lower friction in comparison to mineral oil-based products. This provides better lubrication at low start-up temperatures. Shell Omala S4 GXV Plus can operate in high flow rate systems with filtration as low as 3 micron mesh size per validation with extended OEM filterability tests.
Excellent compatibility with seals, paints and sealantsShell Omala S4 GXV Plus is recommended for industrial reduction gear systems using a wide range of seals, including nitrile rubber and fluoro-elastomers. Shell Omala S4 GXV Plus meets the demanding requirements of both Flender and SEW for their gearboxes and gear motors.
