Manufacturer's description

Premium quality industrial gear oils. Shell Omala F oils are premium quality, lead-free, extreme-pressure oils designed, primarily, for the lubrication of heavy duty industrial gears. Their high load carrying capacity and anti-friction characteristics combine to offer superior performance in gears and other industrial applications. They are formulated using high viscosity index, solvent refined, base oils and incorporate a special sulphur-phosphorus additive to provide an extreme pressure performance significantly better than that provided by leaded gear oils. Shell Omala Oil F 220 is the ISO VG 220 grade: typical kinematic viscosity 220 cSt at 40 °C and 19.4 cSt at 100 °C, viscosity index 100, pour point -18 °C.

Applications

• Industrial gear drives where a full EP performance is required.
• Shell Omala F should not be used for automotive hypoid gears. The appropriate Shell Spirax Oil should be used for this purpose.
• Shell do not recommend/support use in systems with fine filtration (<10 microns) because sustained foam control performance is not assured. Please consult your Shell Local Technical Advisor and Product Application Specialist.
• Steel gear transmissions
• Circulating and splash lubricated systems

Performance & benefits

• Excellent load carrying and anti-friction characteristicsReduces gear tooth and bearing wear on both steel and bronze components. The load carrying capacity of Shell Omala F Oils, as determined in laboratory tests, is significantly better than that of leaded gear oils. Gear tooth wear is reduced, particularly under conditions of high load. Typical test results for Shell Omala F 220 are:
• Extreme Pressure PropertiesTimken Wear & Lubricant Testing Machine: IP 240 / ASTM D2782 OK Load lbs = 60 mins
• Four Ball Extreme Pressure TestInitial seizure load kg IP 239/79 = 250 kg
• Load Carrying CapacityFZG Gear Machine: IP 334 A/8.3/90 and A/16.6/90 Failure Load Stage = >12
• Outstanding oxidation and thermal stabilityWithstands high thermal loading and resists the formation of sludge and other harmful products of oxidation. Extended oil life, even with bulk oil temperatures up to 100 0 C in certain applications.
• Effective corrosion inhibitionProtects both steel and bronze components, even in the presence of contamination by water and solids.
• Resistant to micro-pittingStandard setting anti micro-pitting performance to reduce the risk of premature failure through surface distress.
• Wide range of viscositiesCaters for the most varied and arduous industrial applications.
• Lead-freeOperator acceptability. Reduced health risk.
• Water shedding propertiesShell Omala F Oils have excellent water separation properties. Excess water can be drained easily from lubrication systems. (Water can greatly accelerate surface fatigue on gears and bearings as well as promoting ferrous corrosion on internal surfaces. Water contamination should be avoided or removed as quickly as possible after the occurrence).
• Heater CapacityThe capacity of heaters, used to raise bulk oil temperatures, should not exceed 11.5 KJ/m2 (7.5 W/in2).
• Sufficient oxidation stability for a lifetime of 10,000 hours or two years at 80 0 C
• A pass in the FVA-54/II micro pitting (grey staining) test at 0 load stage 10 at 90 C
• A load stage 12 pass in the FZG double speed test ( DIN 51354 Part 2)
• Change-over Procedures The following procedures and precautions are recommended when changing oils - including leaded grades:-As a general principle, oil that has been in use for some time should be renewed completely. For complete benefit, Shell Omala F should be not be mixed with other oils
• Gearboxes Drain the gearbox completely and inspect internally. Remove any sludge deposits manually. Flush the gearbox with new oil. Drain and refill with the appropriate viscosity Shell Omala F oil
