Shell Aviation can offer a range of aviation greases designed to fill almost every lubrication need of the aviation community. There follows very brief descriptions of the major products in the AeroShell Grease range. Other, specialist greases can be made available; please check with your local AeroShell supplier.

AeroShell Grease 5

Wheel Bearing and Engine Accessory Grease

asg 5

Microgel thickened, mineral oil base

Combines high load-carrying ability with excellent resistance to water and high temperatures. It inhibited against corrosion and oxidation, and has a useful temperature range of -23°C to + 177°C. Used primarily in aircraft wheel bearings and engine accessories operating at high speeds and relatively high temperatures.

AeroShell Grease 6

General Purpose Airframe Grease

asg 6

Microgel thickened, mineral oil base

Inhibited against corrosion and oxidation, it features outstanding low temperature torque properties and resistance to water. Useful temperature range of -40°C to +121°C. Used primarily in plain and anti-friction bearings on general aviation aircraft.

AeroShell Grease 7

Advanced Multipurpose Airframe Grease

asg 7

Microgel thickened, synthetic diester oil base

Corrosion inhibited and fortified to resist oxidation, it combines excellent load-carrying capacity with a useful temperature range of -73°C to + 149°C. Recommended for highly loaded gears and actuator screw mechanisms, as well as for instrument and general airframe lubrication.

AeroShell Grease 14

Leading Multipurpose Helicopter Grease

asg 14

Calcium soap thickened, mineral oil base

Inhibited against corrosion and oxidation, it is compounded with special anti-rust additives, and gives outstanding protection against fretting and moisture corrosion. Useful temperature range is -54°C to +93°C. Approved by all leading helicopter manufacturers. Recommended for most helicopter main and tail rotor bearings; widely used as a general purpose helicopter grease

AeroShell Grease 15

Extreme Temperature Ball and Roller Bearing grease

Teflon thickened, silicone oil base

Inhibited against corrosion and oxidation, it possesses excellent high temperature and mechanical stability properties, low evaporation rate and superior resistance to water wash-out. Intended for lightly loaded ball and roller bearings over a temperature range of -73°C to +232°C. Recommended for continuous high temperature service, e.g. in turbine engine controls, and for low temperature applications where low torque properties are required.

AeroShell Grease 22

Versatile Multipurpose Grease

asg 22

Microgel thickened, synthetic hydrocarbon oil base

Corrosion inhibited and fortified against oxidation, it has excellent anti-wear properties, load-carrying capacity and water resistance, plus a wide useful temperature range of -65°C to +204°C. Recommended for aircraft wheel bearings, engine accessories and airframe lubrication, and for anti-friction bearings operating at high speeds and at high or low temperatures.

AeroShell Grease 33

Universal Airframe Grease

Lithium complex thickened, synthetic hydrocarbon/ester oil base

Developed with the purpose of satisfying almost all airframe lubrication requirements with a single grease. Its enhanced corrosion resistance and load-carrying capacity reduces wear and tear and can lead to extension of re-greasing intervals and reduction in maintenance costs. Replacing several greases with a single grease avoids the risk of misapplication and also reduces stock inventory, again providing cost savings. Useful temperature range is -73°C to +121°C.

AeroShell Grease 33MS

An Extreme pressure (EP) Grease

asg 33ms

AeroShell Grease 33MS is an extreme pressure (EP) grease based on the proven lithium complex technology of AeroShell Grease 33, and is fortified with 5% Molybdenum Disulphide.  The benefits of Grease 33MS include: Improved anti-wear and corrosion resistance over AeroShell Grease 17; It is fully compatible with AeroShell Grease 33, so reduces the risks and problems associated with misapplication; Load carrying and EP properties equal to that of the well established AeroShell Grease 17; Fully approved to MIL-G-21164D.  

It possesses enhanced anti-wear and anti-corrosion properties and is particularly suitable for lubricating heavily loaded sliding steel surfaces, such as, for example, bogie pivot pins on aircraft landing gear-assemblies.  AeroShell Grease 33MS is a direct alternative to AeroShell Grease 17, but when changing from (clay-based) ASG 17 to (Li-complex based) ASG 33MS, the normal rules on grease changing should be applied.
