AeroShell 33 Grease 14 Oz Tube
FREE Shipping
Overview
| 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. |

Applications
For many years aircraft operators have been seeking to rationalize the greases used on aircraft and to reduce the number of different greases in their inventories. Recently Boeing began research on a new, general purpose, corrosion-inhibiting grease. The aim was for a non-clay based grease that would provide longer life for components and mechanisms and possess improved wear and corrosion resistance. This led to the introduction of the new Boeing Specification BMS 3-33.
Owing to the wide range of operating temperatures, loads and other environmental conditions required for various aircraft components, several different types of grease with different desirable properties are used during routine lubrication of aircraft components. Boeing, in developing their BMS 3-33 specification, took account of the properties of the different grease types used on aircraft and wrote a specification for a grease which would provide improved performance and which could be used in the widest possible range of grease applications. That performance level has largely been adopted as the SAE AMS 3052 specification, which is in turn the basis for the Airbus AIMS 09-06-002 specification.
AeroShell Grease 33 is approved to BMS 3-33B and offers the improved performance properties required by this specification and the other specifications mentioned above.
AeroShell Grease 33 can be used for routine lubrication on Boeing aircraft where MIL-PRF-23827C or BMS 3-24 is specified. AeroShell Grease 33 can also be used in some applications on Boeing aircraft which require use of MIL-G-21164. Other applications on Boeing aircraft which require use of MIL-G-21164 and other greases are being reviewed and in due course Boeing will issue details of the full range of applications. For the current status, refer to the latest issue of Boeing Service Letter “BMS 3-33 General Purpose Aircraft Grease”.
AeroShell Grease 33 can be used for routine lubrication in applications where MIL-PRF-23827C is specified on aircraft manufactured by McDonnell Douglas, Airbus, BAe Regional Aircraft, Canadair, Lockheed, Embraer, Fokker and Gulfstream (except for wheel bearings, applications above 121°C and sliding applications requiring molybdenum disulphide).
Other aircraft manufacturers are evaluating AeroShell Grease 33 with the aim of approving it for use on their aircraft. Operators should regularly check with these manufacturers for the latest status.
Use of AeroShell Grease 33 can provide operators with the following benefits:
- Reduced inventories
- Easier maintainability (one major grease for most applications)
- Reduced maintenance labour costs
- Less chance of product mis-application

Been using this since about 2018. Aeroshell 33 is a general purpose lithium based, rather than clay based grease. As such, it can be used in most locations other than wheel bearings. When old, the 33 dries out differently in that there is less of a tendency for the greased parts, or more correctly, not recently greased parts to dry full of solids like the Microgel clay based greases. New, the grease is a green colour and as old grease tends to be black in colour, it is easier to determine when new 33 has displaced the old grease. It is also a good cold weather grease as well as hot weather. (-100F to +250F) Lately ACS and all others has had difficultly with the availability of 33, hence I order about six months ahead and keep at least two tubes (my years supply) in my own stock.

Great all-around airframe grease. Looks blue/green to my partially color-blind eyes, but still stands out from the dirty old brown grease its pushing out of the joints at zerks. Spreads easily with a brush/finger as well.
