High quality industrial gear and bearing oils
Shell Omala is a high-quality, lead-free, high-pressure, anti-seize oil designed to lubricate heavy duty industrial gears. High bearing capacity and antifriction characteristics allow the successful use of these oils in gears and other applications.
Area of usage
Shell Omala oils, developed on the basis of highly refined base oils with a high viscosity index and compositions of special sulfur-phosphorus additives to impart extreme pressure properties, can be successfully used in the following areas:
- Steel Gear Transmissions
- Industrial gears requiring anti-seize oils
- Bearings
- Circulation and spray lubrication systems
Shell Omala oils cannot be used in automotive hypoid gears. They recommend the use of Shell Spirax family oils.
Advantages
- Excellent oxidation and heat resistance
Resist thermal stress, deposits and other harmful oxidation products. Long service life, even at oil temperatures up to 100 ° C in some applications.
- Effective Corrosion Inhibitors
Protect both steel and bronze parts, even in the presence of water and particulate matter.
- Lead free
Less hazardous to personnel health and disposal.
- Wide viscosity range
Oils for the most diverse and most critical nodes.
- Demulsifying properties
Shell Omala oils exhibit high demulsifying properties, so water can be easily removed from the lubrication system. (Water can significantly increase the surface fatigue of gears and bearings, as well as cause corrosion on the internal surfaces of parts. This is why water should not be allowed to enter the oil or should be removed immediately from the system).
- Excellent load bearing capacity
Reduced wear of teeth and bearings, steel and bronze. Laboratory tests show that the load-bearing capacity of Shell Omala oils is significantly higher than that of gear oils containing lead. Tooth wear is significantly reduced, in particular at high loads. Typical Results for Shell Omala 220:
