Description:

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.

Performance, Features and Benefits:
•Excellent load carrying and anti-friction characteristics Reduces gear tooth and bearing wear on both steel and bronze components. 

•Outstanding oxidation and thermal stability 

Withstands 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 1000C in certain applications. 

•Effective corrosion inhibition 

Protects both steel and bronze components, even in the presence of contamination by water and solids. 

•Lead-free 

Operator acceptability. Reduced health risk. 

•Wide range of viscosities 

Caters for the most varied and arduous industrial applications. 

•Resistant to micro-pitting 

Standard setting anti micro-pitting performance to reduce the risk of premature failure through surface distress. 

•Water shedding properties 

Shell 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).  

•Load Carrying Capacity 

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 Properties 

Timken Wear & Lubricant Testing Machine: IP 240/ASTM D 2782 

OK Load lbs = 60 mins 

•Four Ball Extreme Pressure Test 

Initial siezure load kg IP 239/79 = 250 kg 

•Load Carrying Capacity FZG Gear Machine: IP 334 

A/8.3/90 and A/16.6/90 Failure Load Stage = >12 

•Heater Capacity 

The capacity of heaters, used to raise bulk oil temperatures, should not exceed 11.5 KJ/m2 (7.5 W/in2). 

Application:

•Steel gear transmissions. 

•Industrial gear drives where a full EP performance is required. 

•Bearings. 

•Circulating and splash lubricated systems. 

•Shell Omala F should not be used for automotive hypoid gears. The appropriate Shell Spirax Oil should be used for this purpose.
