AeroShell®
 GREASES
Premium military approved greases
for the aviation industry
Product Description
Shell offers a complete line of eight aviation greases designed to fill almost every lubrication need of the
aviation community. The product line consists of eight products each designed for specific applications. Six
of the Shell aviation greases are based on Microgel®, an inorganic thickening agent. The seventh grease is
soap type grease specifically designed to provide the unique lubricant requirements of helicopter main and tail
rotor bearings. The eighth grease is thickened with lithium complex soap and is approved against both
Boeing and military specifications.
Applications
Whenever an aircraft is certified, all of the lubricants are specified for each application point on the type
certificate. The type certificate will specify, either by military specification number or by specific product
names, those products, which are qualified to be used. The FAA regulations state that only products qualified
for specific applications can be used in certified aircraft. Therefore, in aviation it is the responsibility of the
aircraft owner or designated representative to determine which products should be used. Lubricant
recommendation charts for specific aircraft should be consulted, or the original airframe manufacturer should
be contacted for specific product recommendations.
The Products
• AeroShell Grease 5 is high temperature aircraft wheel bearing and engine accessory grease. It is made
with high viscosity base oil and a Microgel
 non-melting inorganic thickener, providing excellent load
carrying ability and resistance to water washout. It has a useful temperature range of -10° F (-23° C) to
+350° F (+177° C). This grease is increasingly being used in high temperature industrial applications,
such as drying ovens. AeroShell Grease 5 is qualified under the former MIL-G-3545C (obsolete)
specification.
• AeroShell Grease 6 is general-purpose airframe grease used primarily in plain and anti-friction bearings.
It is made with a Microgel
 inorganic thickener, which provides outstanding low temperature torque
properties and resistance to water. It has a useful temperature range of -40° F (-40° C) to +250° F
(+121° C). It is also used in other non-aviation applications requiring excellent low temperature
lubrication properties. AeroShell Grease 6 is qualified under MIL-G-24139A and MIL-G-7711A
(obsolete) specifications.
• AeroShell Grease 7 is low temperature multipurpose aviation grease recommended for instruments and
general airframe lubrication of turbine powered aircraft as well as highly loaded gears and actuator screw
mechanisms. It is made with synthetic diester base oil and a Microgel
 non-melting inorganic thickener,
which provides a useful temperature range of -100° F (-73° C), to +300° F (+149° C). AeroShell Grease
7 is qualified under the MIL-PRF-23827C specification.• AeroShell Grease 14 is the leading multipurpose helicopter grease used for most helicopter main and tail
rotor bearings (where specified). It is made with mineral base oil and a calcium soap thickener which
provides outstanding protection against moisture, corrosion & fretting. It has a useful temperature range
of -65° F (-54° C) to +200° F (+93° C). AeroShell Grease 14 is qualified under MIL-G-25537C
specification.
• AeroShell Grease 16 is a superior anti-friction bearing grease recommended for anti-friction bearings
operating under load at high speeds and high or low temperatures. It is made with a blend of synthetic
polyolester and mineral oil and Microgel non-melting inorganic thickener, which provides long life and
high water resistance. It has a useful temperature range of -65°F (-54°C) to +400°F (+204°C).
AeroShell Grease 16 is qualified under MIL-G-25760A (obsolete) and Boeing Materials Specification
BMS 3-24A.
• AeroShell Grease 17 is extreme pressure multipurpose grease recommended for heavily loaded sliding
steel surfaces where protection against seizure and corrosion is desired; e.g. bogie pivot pins on jet aircraft
landing gear assemblies. It is made with synthetic diester base oil, molybdenum disulfide and Microgel
non-melting inorganic thickener, which provides outstanding anti-friction bearing lubrication. It has a
useful temperature range of -100° F (-73° C) to +300° F (+149° C). AeroShell Grease 17 is qualified
under MIL-G-21164D specification.
• AeroShell Grease 22 is versatile multipurpose grease recommended for aircraft wheel bearings, engine
accessories and airframe lubrication, and for general anti-friction bearings operating at high speeds and at
high or low temperatures. It is made with synthetic base oil and Microgel
 non-melting inorganic
thickener, which provides excellent anti-wear properties and load carrying capacity. It has a useful
temperature range of -85° F (-65° C) to +400° F (+204° C). AeroShell Grease 22 is qualified under
MIL-PRF-81322F Grade 2 and DOD-G-24508A specifications.
• AeroShell Grease 33 is multipurpose airframe grease specifically developed for Boeing to be used in
roller bearings, actuator screws and other airframe equipment. It is made with synthetic base oil and a
Lithium Complex thickener, which provides enhanced corrosion resistance and load-carrying capacity. It
has a useful temperature range of -100° F (-73° C) to +250° F (+121° C). AeroShell Grease 33 is
qualified under MIL-PRF-23827C and Boeing Specification BMS 3-33A. Typical Properties of Shell Aeroshell Greases
