Applications
AeroShell Grease 33 is approved to BMS 3-33C and offers the improved performance properties required by this specification.
AeroShell Grease 33 can be used for routine lubrication in applications where MIL-PRF-23827C is specified on aircraft manufactured by Airbus, Boeing, Embraer, Fokker, Gulfstream and other legacy OEMs like McDonnell Douglas, BAe Regional Aircraft (except for wheel bearings, applications above 121°C and sliding applications requiring molybdenum disulphide).
AeroShell Grease 33 can also be used in some applications on 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 3-33C General Purpose Aircraft Grease”.
