DESCRIPTION
SELCO SG-370 is manufactured from a synthesized
hydrocarbon fluid and a non-soap thickener.
Its consistency is between an NLGI No.1 and
No.2. It offers outstanding performance over
wide temperature ranges, with the excellent
retention and resistance to high-temperature
degradation. In addition, it resists water
washing, provides superior load-carrying ability,
reduces frictional drag, and prevents excessive
wear.
Other tests show that SELCO SG-370 prevents
friction oxidation (fretting) and lubricates
rolling element bearing under conditions of
high speeds and temperatures. It has also
shown superior ability to lubricate heavily
loaded sliding mechanisms, such as wing flap
screwjacks.
APPLICATION
SELCO SG-370, is designed for the lubrication
of plain and rolling bearings at low to high
speeds, and splines, screws, worm gears, and
other mechanisms, where high friction reduction,
low wear, and low lubricant friction losses
are required. It provides minimum resistance
to starting at extreme low temperature (down
to -54° C/ -65° F.), as well as low
running torque.
SELCO SG-370, is recommended for use in
landing wheel assemblies, control systems
and actuators, screwjacks, servo devices,
sealed-bearing motors, oscillating bearings,
and helicopter rotor bearings on military
and civil aircraft and on naval shipboard
auxiliary machinery. It is also recommended
for industrial lubrication, including sealed
or repackable ball and roller bearings wherever
extreme temperature conditions, high speeds,
or water washing resistance are factors.
Typical applications include conveyor bearings,
small alternator bearings operating at temperatures
near 177° C. (350° F.), high-speed
miniature ball bearings, and bearing situations
where oscillatory motion, vibration, and
fretting create problems.
