AeroShell Grease 33AeroShell Grease 33 is a synthetic universal airframe grease composed of a lithium complex thickened synthetic base oil with corrosion and oxidation inhibitors and load carrying additives.
The useful operating temperature range is -73°C to +121°C.
. AeroShell Grease 33 can be used for routine lubrication in . For many years aircraft operators have been seeking to applications where MIL-PRF-23827C is specified on aircraft rationalise the greases used on aircraft and to reduce the manufactured by McDonnell Douglas, Airbus, BAe Regional number of different greases in their inventories. Recently Aircraft, Canadair, Lockheed, Embraer, Fokker and Gulfstream Boeing began research on a new, general purpose, corrosion- (except for wheel bearings, applications above 121°C and inhibiting grease. The aim was for a non-clay based grease sliding applications requiring molybdenum disulphide).
that would provide longer life for components and Other aircraft manufacturers are evaluating AeroShell Grease mechanisms and possess improved wear and corrosion 33 with the aim of approving it for use on their aircraft.
resistance. This led to the introduction of the new Boeing Operators should regularly check with these manufacturers for Owing to the wide range of operating temperatures, loads Use of AeroShell Grease 33 can provide operators with the 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 Less chance of product mis-application.
BMS 3-33B specification, took account of the properties of the Specifications, Approvals & Recommendations 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 . AeroShell Grease 33 is approved to BMS 3-33B and offers the For a full listing of equipment approvals and recommendations, improved performance properties required by this please consult your local Shell Technical Helpdesk, or the OEM . AeroShell Grease 33 can be used for routine lubrication on Compatibility & Miscibility Boeing aircraft where MIL-PRF-23827C or BMS 3-24 is . AeroShell Grease 33 contains a synthetic oil and must not be specified. AeroShell Grease 33 can also be used in some used with incompatible seal materials.
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 3-33B General Purpose Aircraft Bomb Oxidation pressure drop from 758 kPa (110 psi) @99°C Bomb Oxidation pressure drop from 758 kPa (110 psi) @99°C These characteristics are typical of current production. Whilst future production will conform to Shell's specification, variations in Health, Safety & Environment.
