Itis formulated using a synthetic polyalkylene glycol base oil, which isdesigned to help maximise worm-gear life and efficiency. Real-worldapplications show that this oil can offer you excellent oil life and wearprotection for worm and spur gears, thus helping you to increaseproductivity and cut maintenance costs. Shell Omala S4 WE is widelyrecognised and approved by leading equipment manufacturers.Designed to protectProtecting gears from damage can help to increase service life and maximise your return on investment. Shell Omala S4 WE can help toachieve this by offeringn up to 70% less worm-gear wearthan Shell Omala S1 Wn up to 45% less spur-gear wearthan Shell Omala S1 W.Shell OmalaS4 WE 320Up to 70% less worm-gear wearShell Omala S4 WE 460Up to 45% less spur-gear wearShell Omala S1 W 460Shell Omala S1 W 4600 2040 6080100Better protectionBacklash wear (% of Shell Omala S1 W 460)(David Brown Radicon 500-hour wear test)0 2040 6080100Better protectionSpur-gear wear (% of Shell Omala S1 W)(FZG 60-hour wear test, ASTM D4998)

Designed for long oil lifeLimiting fluid degradation can help to prolong oil life. Shell Omala S4 WE is designed to help you operate for longer without interruption –for reduced maintenance requirements and enhanced productivity. In an industry-standard oil life test, Shell Omala S4 WE hasn over twice the oil lifecompared with conventional oils such as Shell Omala S1 W.Shell Omala S4 WE 460Shell Omala S1 W 460Over twice the oil life0 50 100150 200250Longer lifeOil life (% of Shell Omala S1 W)(RPVOT – modified ASTM D2272 test at 120°C)Designed for high efficiencyA gear oil needs to protect and lubricate efficiently. Shell Omala S4 WE is designed to increase productivity by helping equipment to meetor exceed its design capabilities. Shell Omala S4 WE hasn over 10% greater worm-gear efficiencythan a standard mineral oiln a 75% lower friction coefficientthan conventional oils such as Shell Omala S1 W.Shell Omala S4 WE 320Shell Omala S4 WE 46075% lowerMineral oilOver 10% greater efficiencyShell Omala S1 W 4600 20 40 60 80 100Greater efficiencyWorm gear efficiency (%)(David Brown Radiconworm-gear efficiency test)0 0.01 0.02 0.03 0.04Lower is betterFriction coefficient20% slide/roll ratiosimulating typical gearcontact conditionsSpecifications and approvalsShell Omala S4 WE meets the requirements of a wide range of industrial bodies andequipment manufacturers, and is available in viscosity grades from ISO 150 to 680.Claims and approvalsFully approved by BonfiglioliApplicationsMeets requirementsANSI/AGMA 9005-E02 (EP)David Brown S1.53.105 GISO 12925-1 Type CKEIndustrial worm-drive reduction systems – for use in severe operatingconditions such as high load under extreme temperature conditions.Compared with conventional oils, Shell Omala S4 WE can significantlyreduce energy loss in worm drives.Extended life operations – for long-life applications, particularly whereexceptional protection is required for inaccessible locations, for example,in wind turbine yaw bearings or where high temperatures or pressures maybe encounteredSuitable for bearings and other components in splash-lubricated systemsContains polyalkylene glycols and is not compatible with mineral oilsor many synthetic oils.
