AEROSHELL Grease 64 is available in 14 oz
grease gun cartridges & 37.5 pound pails.
AEROSHELL Grease 64 shares the same
advanced grease technology AeroShell Grease 33, AeroShell Grease 64 also
possesses the extreme pressure (EP) characteristics provided by molybdenum
disulphide. This grease contains a synthetic oil and must not be used with
incompatible seal materials.
AeroShell Grease 64 comprises AeroShell Grease 33 fortified
with 5% molybdenum disulphide. It possesses the
enhanced anti-wear and anti-corrosion properties of AeroShell Grease 33 with the
added EP (Extreme Pressure)
properties provided by the addition of a solid lubricant.
The useful operating temperature range is –73°C to +121°C.
APPLICATIONS
AeroShell Grease 33 has established itself as the answer to most of the
airframe’s General Purpose, airframe greasing
requirements, being approved for use in Boeing, Airbus and many other aircraft
types.
AeroShell Grease 33 sets the standard with
exceptional anti-corrosion and anti-wear performance while allowing aircraft
operators to shrink their grease inventory
and reduce the risk of misapplication. However, there remains a small number of
highly loaded, sliding applications on
the airframe where the additional boost of molybdenum disulphide will always be
required. To address this need, Shell
Aviation has developed AeroShell Grease 64 .
Sharing the same advanced grease
technology as its parent,
AeroShell Grease 64 also possesses the extreme pressure (EP) characteristics
provided by molybdenum disulphide.
AeroShell Grease 64 contains a synthetic oil and must not be used with
incompatible seal materials.
