Shell Gadus S3 T150 J
Premium quality industrial bearing greases
Shell Gadus S3 T150 J Greases are high technology greases designed to give optimum
performance for grease lubrication in industrial bearings.
They are based on mineral oil with a special diurea thickener to give long life, low
wear and shear-stable properties at high temperatures.
In high temperature applications Shell Gadus S3 T150 J Greases will outperform even
fully synthetic (PAO) lithium complex greases proposed in the market
Applications
Shell Gadus S3 T150 J greases are particularly
recommended for use in high temperature
(150°C), lightly loaded industrial bearings. It is
recommended for use where long operational life
and extended re-greasing intervals are an
important consideration, for example in Steel Mill
applications

loss of protection
Zinc-free formulation
 For use in steel plants using reheat furnaces
requiring a zinc-free formulation.
High Temperature Performance
The diurea thickener used in Shell Gadus S3
T150 J greases have a high melting point and the
grease performance is limited only by the
properties of the base oil and additive
components.
Corrosion Protection
When a bearing is running, most high quality
greases can maintain an adequate lubricating
film even when the grease is loaded with water.
However when the grease bearing is idle
corrosion may occur causing pitting which can
be destructive.  Shell Gadus S3 T150 J greases
are formulated with corrosion inhibitors to help
protect bearing surfaces even when the grease is
contaminated with water.
The lubrication properties of Shell Gadus S3
T150 J greases are unimpaired by small
quantities of salt water.
Load Carrying Capacity
Although not specifically designated extreme
pressure, Shell Gadus S3 T150 J greases have
been used very successfully in slow moving,
loaded large bearings such as those found in
Continuous casters in steel plants:
Operating Temperature Range
-20°C to +150°C
With caution, Shell Gadus S3 T150 J greases
may, in some circumstances, be used at
temperatures up to 180°C, but only if the re-
lubrication period is suitably adjusted.

Re-lubrication
Grease life varies considerably from application
to application, even with bearings operating
under nominally identical conditions.  Variables
such as air flow, dirt and humidity can have a
considerable effect in addition to the more
commonly recognised parameters of load, speed
and temperature.
The use of Shell Gadus S3 T150 J greases usually
permits considerable extension of the re-
lubrication interval.
Oxidation Stability
Shell Gadus S3 T150 J greases have a superior
high temperature oxidation inhibitor system to
ensure that they will withstand high operating
temperatures without forming deposits.  Unlike
the soap thickeners used in most greases, the
diurea thickener in Shell Gadus S3 T150 J
greases does not catalyse grease oxidation,
indeed the diurea thickener offers inherent anti-
oxidant properties.  This contributes to longer
grease life at higher temperatures.
The base oil component of Shell Gadus S3 T150
J greases is a specially selected high viscosity
index mineral oil with excellent oxidation and
evaporation resistance.
Sealing
The rheology of Shell Gadus S3 T150 J greases
is such that at low shear rates and with heating
the consistency increases.  Consequently, in
bearings operating at high temperatures the
grease remains in place providing good sealing
and continuous lubrication even in the presence
of vibration.
Water Washout
Shell Gadus S3 T150 J greases exhibit very good
resistance to water washout by immersion or
spray.
Health & Safety
Shell Gadus S3 T150 J greases are unlikely to
present any significant health or safety hazard
when properly used in the recommended
application, and good standards of industrial
and personal hygiene are maintained.

These characteristics are typical of current production. Whilst future production will
conform to Shell’s specification, variations in these characteristics may occur.
