SYNTHETIC LUBRICATING GREASE
|
|
DESCRIPTION
SELCO SG-360 is high-performance grease, which
combines a synthesized hydrocarbon base fluid
with a lithium complex soap thickener. The
thickener system provides a high dropping
point, excellent resistance to water wash,
and a tenacious structural stability. The
unique physical properties of the synthetic
base oil, combined with selected additives,
provide outstanding protection against wear,
rust, corrosion, and high-temperature degradation.
The wax-free feature of the synthetic base
oil allows for low-temperature mobility/ pumpability
and very low starting and running torque values.
Also, the traction property of the synthetic
base fluid is considerably lower than mineral
oil, allowing for temperature reductions in
the load zone of rolling element bearings.
APPLICATION
SELCO SG-360 is recommended for aviation applications
which need a lubricant that can perform normal
functions yet go far beyond in terms of high
and low temperature and long-life performance.
It is NLGI Grade 2 grease having the cold-temperature
pumping resistance of most mineral oil NLGI
Grade 0 greases. It is true wide-temperature,
multi-service grease.
TYPICAL CHARACTERISTICS
Physical characteristics are listed in the
