SHELL OMALA®
OILS
High quality industrial gear ａnd bearing oils
Product Description
Shell Omala Oils are high quality, extreme-pressure oils designed for the lubrication of heavy-duty industrial gears.
Their high load carrying capacity ａnd anti-friction characteristics combine to offer exceptional performance in gears
and other industrial applications including some mist applications.
Shell Omala Oils help reduce gear tooth ａnd bearing wear on both steel ａnd bronze components. The load carrying
capacity of Shell Omala Oils, as determined in laboratory tests, meets Shell’s stringent requirements to be offered
globally. The additive system helps to reduce gear tooth wear, particularly under conditions of high load. Shell Omala
Oils are suitable for spur, helical ａnd bevel gears ａnd are designed to operate under conditions of heavy ａnd shock
loads.
Shell Omala Oils withstand elevated temperatures ａnd resist the formation of sludge. The formulation helps provide
extended oil life even under higher than normal operating temperatures. Shell Omala Oils protect both steel and
bronze components, even in the presence of contamination by water ａnd solids. Shell Omala Oils also have
excellent water separation properties, such that excess water can be drained easily from lubrication systems. Water can
greatly accelerate surface fatigue with gears ａnd bearings as well as promoting ferrous corrosion on internal surfaces.
Water contamination should therefore be avoided or removed as quickly as possible after the occurrence.
Shell Omala Oils are formulated using high viscosity index base oils, ａnd incorporate a special sulfur-phosphorus
additive to provide extreme pressure performance.
They are available in several ISO viscosity grades ranging from 68 to 3200.
Applications
• steel gear transmissions including spur, helical ａnd bevel gears
• industrial gear drives where full extreme pressure performance due to heavy or shock loading is needed
• plain ａnd roller contact bearings
• circulating ａnd splash lubricated systems
• mist systems
Note: For automotive hypoid gears, use the appropriate Shell Spirax®
Heavy-Duty or Shell Spirax®
S lubricant.
Performance Features ａnd Benefits
• outstanding oxidation ａnd thermal stability which helps extend oil life
• effective corrosion inhibition to help protect gearbox components
• effective sulfur-phosphorus extreme pressure system to prevent wear under tough conditions
• wide range of viscosities to meet a wide variety of operating conditions
• excellent water shedding properties which allow the water to separate ａnd be drained protecting components
from rust ａnd corrosion
• excellent load carrying capacity helping to extend equipment life
