Aeroshell Grease 33

Product Description

AeroShell Grease 33 can be used for routine lubrication on Boeing aircraft for applications where MIL-PRF-23827C or BMS 3-24 is specified. It can also be used in some applications on Boeing aircraft which require use of MIL-G-21164D. Other applications on Boeing aircraft which require use of MIL-G-21164D and some other greases are being reviewed and in due course Boeing will issue details of the full range of applications.
 
This grease can be used for routine lubrication in applications where MIL-PRF-23827C is specified on aircraft manufactured by McDonnell Douglas, Airbus Industrie, BAe Regional Aircraft, Fokker and Gulfstream (except for wheel bearings, applications above 121°C and sliding applications requiring molybdenum disulphide).
 
Other aircraft manufacturers, such as Canadair, Saab and Lockheed 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.
 
The following pictures illustrate the superior load-carrying and anti-corrosion properties of AeroShellGrease 33 (green) when compared with a competitive grease meeting the MIL-PRF-81322F specification (red):

 
Four-Ball EP test (ASTM D2596)
One test ball rotates on three fixed balls in a cup filled with grease
Load: 160kg; Speed: 1770 rpm
Duration: 10 seconds, or until weld occurs, whichever comes first
AeroShell Grease 33 - small wear scars
Competitor grease - lubrication failure and welding

 
Timken EP Test (ASTM D2509)
Test cup rotates on test block under load while being continuously fed with fresh grease
Load: 40lbs; Speed: 800rpm
Duration: 10 minutes, or until noise and vibration indicate failure, whichever comes first.
Wear scar measured on completion of test
AeroShell Grease 33 - small wear scar
Competitor grease - large wear scar

 
Corrosion Prevention (Modified ASTM D1743)
Bearings: Timken cone and roller assembly
Procedure: bearings packed with test grease and rotated under light load for 60 seconds, then submerged in 3% salt solution for one minute and then stored at 52ºC and 100% humidity for 12 hrs. Bearings disassembled and bearing races examined for rust.
AeroShell Grease 33 - no corrosion
Competitor grease - corrosion between rollers and race
