Specification of SHELL OMALA S2 G 220 20L
Shell Omala S2 G oils are high quality 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.
Performance, Features & Benefits
Performance Benefits can be summarised in OMALA. C O M
(Protection against Contamination, Oxidation and Micropitting) Handling Contamination and hence maintaining system efficiency
· Shell Omala S2 G oils display a combination of excellent water shedding capability and low foaming tendency. The oils are designed to minimize the potential for foaming in the most testing of environments.
Shell Omala S2 G oils have excellent water separation properties, such that excess water can be drained easily from lubrication systems to help extend the life of the gears and ensure efficient lubrication of the contact areas. Water can greatly accelerate surface fatigue of 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.
Long oil life through Oxidation stability – leading to maintenance saving
· Shell Omala S2 G oils are formulated to reduce the risk of thermal and chemical breakdown throughout the maintenance interval. They withstand high thermal loading and resist the formation of sludge to provide extended oil life capability,
even with bulk oil temperatures of up to 100oC in certain applications.
Excellent wear & corrosion protection incl. protection against Micro-pitting
· Shell Omala S2 G oils have superb load carrying capacity that helps reduce gear tooth and bearing wear on steel components.
Shell Omala S2 G oils offers:
Excellent micropitting performance to help prolong component life.
· Low sludge tendency, which reduces wear on rollers and helps
ensure bearing protection
· Outstanding corrosion protection, protecting steel components, even in the presence of contamination by water and solids.
· Shell Omala S2 G oils offers excellent shear stability by maintaining its viscosity, thereby protecting the component from friction and wear.
Main Applications Enclosed industrial gear systems
· Shell Omala S2 G technology provides an extreme EP system which allows trouble-free application in most enclosed industrial gearboxes using steel spur and helical gear drives with circulation or splash lubrication systems.
Highly loaded gears
· Shell Omala S2 G oils have an effective full extreme pressure (EP) additive system allowing them to be used in highly-loaded gear systems.
Other applications
· Shell Omala S2 G oils are suitable for lubrication of bearings and other components in circulating and splash-lubricated systems For loaded worm drives Shell Omala S4 WE, Shell Morlina S4 B and Shell Omala S1 W are recommended.
For automotive hypoid gears, the appropriate Shell Spirax Oil should be used
