SHC 600 Series lubricants are supreme performance gear and bearing oils
designed to provide outstanding service in terms of equipment
protection, oil life and problem-free operation. They are formulated
from synthesized, wax-free hydrocarbon base fluids. The combination of a
naturally high viscosity index and a unique, proprietary, additive
system enables these products to provide outstanding performance in
extreme service applications at high and low temperatures, well beyond
the capabilities of mineral oils. These products are resistant to
mechanical shear, even in heavily loaded gear and high shear bearing
applications, so that there is virtually no loss of viscosity.
The Mobil SHC 600 Series products have low traction coefficients, which
derive from the molecular structure of the base stocks used. This
results in low fluid friction in the load zone of non-conforming
surfaces such as gears and rolling contact bearings. Low fluid friction
lowers operating temperatures and improves gear efficiency, which
translates into reduced power consumption. It also results in extended
parts life and allows for more economical equipment design. The base
oils used in the Mobil SHC 600 Series have outstanding response to
antioxidant additives resulting in superior resistance to oxidation and
sludging, especially at high temperatures. The additive
combination used in these oils also provides exceptional resistance to
rusting and corrosion, very good antiwear, demulsibility, foam control
and air release properties, as well as multimetal compatibility. The
Mobil SHC 600 Series oils are also compatible with the same seal and
other construction materials used in equipment normally
lubricated with mineral oils.
The leading edge technology on which Mobil SHC 600 Series lubricants has
always been based has made these the products of choice for operators
of a wide range of equipment, worldwide. While initially recognized as a
high temperature problem solver, Mobil SHC 600 Series lubricants are
now used in many marine and industrial applications because of the range
of benefits they offer.
Features and Benefits
The Mobil SHC brand of lubricants are recognised and appreciated around
the world for their innovation and outstanding performance. These
molecular designed synthetic products, pioneered by ExxonMobil research
scientists, symbolize the continuing commitment to advanced technology
to provide outstanding lubricant
products. A key factor in the development of Mobil SHC 600 Series were
the close contacts between ExxonMobil scientists and application
specialists with key OEMs to ensure that this product would provide
exceptional performance in continually evolving industrial equipment
designs.
ExxonMobil's work with OEMs has helped confirm the results from our own
laboratory tests showing the exceptional performance of the Mobil SHC
600 Series lubricants. Not least among the benefits is the potential for
significant efficiency improvements versus mineral oil. These benefits
are particularly evident in equipment
which, by design, cannot avoid low overall efficiency, such as high
ratio wormgears.
To combat high thermal exposure of the oil, proprietary base oils were
carefully selected for Mobil SHC 600 Series oils to obtain exeptional
thermal/oxidative resistance potential. Specific additives which would
maximise the benefits of the base oils were chosen to provide
exceptional oil life and deposit control and resistance to
thermal/oxidative and chemical degradation, as well as the balance of
performance features. The wax-free nature of the base oil also provides
low temperature fluidity characteristcs unmatched by mineral products
and is a key benefit for remote, low ambient temperature applications.
- Superb high temperature thermal/oxidation resistance - Extends equipment high temperature operating
capability Long oil life, reduced need and costs for oil change outsMinimises sludges and deposits for
trouble-free operation and long filter life.
-
High Viscosity Index and absence of wax - Maintains viscosity and film
thickness at high temperatures Exceptional low temperature performance,
including start-up
-
Low traction coefficient - Reduces overall friction and can increase
efficiency in sliding mechanisms such as gearing, with potential for
reduced power consumption and lower steady-state operating
temperatures.Minimises effects of micro-slip
in rolling contact bearings for longer rolling-element life potential
-
High load carrying capability - Protects equipment and extends life; minimizes unexpected downtime and extends service periods
-
Balanced additive combination - Provides excellent performance in terms
of rust and corrosion prevention, water separability, foam control,
air release performance ensuring problem-free operation and reduced
operating costs in a wide range of industrial
and marine applications

Applications:
Mobil SHC 600 Series lubricants are recommended for use in a wide variety of marine and industrial gear and
bearing applications where high or low temperatures are encountered. They are also recommended where
operating temperatures or bulk oil temperatures are such that conventional lubricants give unsatisfactory life,
or where improved efficiency is needed. They are particularly effective in applications where the maintenance
costs of component replacement, system cleaning and lubricant changes are high.
While Mobil SHC 600 Series are compatible with mineral oil based products, admixture may detract from their
performance. Consequently it is recommended that before changing a system to one of the Mobil SHC 600
Series, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits. The
Mobil SHC 600 Series oils are compatible with the following seal materials: fluorocarbon, polyacrylate,
polyurethane ether, some silicone, ethylene/acrylic, chlorinated polyethylene, polysulfide, and some nitrile
rubbers. There is the potential for substantial variations in the elastomers being used today. For best results,
consult your equipment supplier, seal manufacturer, or your local Mobil representative to verify compatibility.
Specific applications include:
- Filled for life gearboxes, especially high ratio/ low-efficiency worm gears
- Remotely located gearboxes, where oil change-out is difficult
- Low and high temperature applications
