AeroShell Grease 22 is a versatile advanced general purpose grease composed of a synthetic hydrocarbon oil thickened with Microgel®, with outstanding performance characteristics. Appropriate additives are included to achieve the necessary oxidation and corrosion resistance, anti-wear properties and load carrying properties. 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.

The useful operating temperature range is –65°C to +204°C.
California Prop 65 Warning Symbol

WARNING: Cancer and Reproductive Harm -


AeroShell Grease 22 is especially recommended for use wherever severe operating conditions are encountered as in high bearing loads, high speeds, wide operating temperature range, and particularly where long grease retention and high resistance to water washout are required.

The wide range of applications include aircraft wheel bearings, engine accessories, control systems, actuators, screw-jacks, servo mechanisms and electric motors, helicopter rotor bearings, instruments, airframe lubrication, hinge pins, static joints, landing gears.

AeroShell Grease 22 contains a synthetic hydrocarbon oil and should not be used in contact with incompatible seal materials. Refer to the General Notes at the front of this section for further information.

It is a/the grease that can be used on every part of a 1955 Bonanza. By the aircraft maint. manual. From Airframe to wheel bearings and electric prop pitch change bearing. However, almost every year it is on back order from Spruce. Just when I need it! Mobile 28 is a recommended substitute by the American Bonanza Society.

It’s my understanding that this is the recommended grease by Cleveland. Well I have been using Aeroshell 5 exclusively. I recently tried 22, and am NOT impressed. I removed bearings after 30 hours to do a tire rotation and found the grease had slicked off the bearing and they looked dry. These bearings where allowed to dry completely after cleaning with mineral spirits. The aircraft manufacture recommends Aeroshell 6, but I find it cannot handle temps above 75 degrees and turns to liquid. I may try the Mobil product, but most likely will continue to use 5.
