GENERAL DESCRIPTION
Design changes in equipment to increase efficiency
are placing importance on correct gear lubrication.
Gear systems are operating under heavier load
conditions and higher RPM's. Many gear systems
are being reduced in size but are forced to
transmit more power. Petroleum gear oils have
done a good lubrication job in most applications;
however recent equipment design changes have
made it evident that synthetic gear oils proving
to be the only lubricant to offer sufficient
gear train protection.
SF-400 series contain a combination of the
latest technical advances in both synthetic
base stocks and complex additive systems to
insure long lasting superior protection. The
superior oxidation stability of SF-400 Series
gear lubricants allows longer intervals between
oil changes. The thermal stability of these
lubricants provides protection at elevated
temperature levels were most petroleum oils
fail.
Actual tests show that SF-400 Series can withstand
30% higher loads than petroleum gear oils.
The superior anti-wear and extreme pressure
properties of the synthetic base material
of these lubricants are enhanced by proprietary
additives to ensure low wear rates.
The cold temperature flow properties of SF-400
Series offer advantages in startup of critical
equipment. When compared to an SAE 90 weight
petroleum gear oil it reduced torque requirement
for cold weather start-up an amazing 36%.
This test was conducted in a Boston right
angle drive gear box to determine the required
torque to slowly turn the drive shaft of the
gear box at 49 °F - 52 °F. The superior
cold flow properties of SF-400 Series offers
the user the advantage of using the correct
viscosity gear lubricant while eliminating
delays due to start-up problems.
RECOMMENDED USAGE
SF-400 Series gear lubricants are designed
for all gear boxes. These lubricants are truly
"multipurpose" gear oils with no
compromise on performance. In dynamo meter
testing SF-400 reduced the tranlational friction
sufficiently to allow almost a 10% increase
in horsepower. Additionally, reduced friction
provides a cooler running differential.
SF-400 Series are recommended for heavy duty
truck transmissions and differentials. Truck
transmissions and differentials will run cooler
and obtain better fuel economy. Over heating
of axles and transmissions can be eliminated.
SF-400 has provided superior lubrication in
gear boxes in a large paper mill for over
one year. The oil drain interval has been
extended from the normal 6 months, to over
one year. Gear wear has proven to be extremely
low and operating temperatures have been greatly
reduced.
