AeroShell Grease 33MS is an extreme pressure grease based on the proven lithium complex technology of AeroShell Grease 33, and is fortified with 5% Molybdenum Disulphide. AeroShell - 33MS Extreme Pressure Grease Benefits: Improved anti-wear and corrosion resistance over AeroShell Grease 17 It is fully compatible with AeroShell Grease 33, so reduces the risks and problems associated with misapplication Load carrying and EP properties equal to that of the well established AeroShell Grease 17 Fully approved to MIL-G-21164D It possesses enhanced anti-wear and anti-corrosion properties and is particularly suitable for lubricating heavily loaded sliding steel surfaces, such as, for example, bogie pivot pins on aircraft landing gear-assemblies. AeroShell Grease 33MS is a direct alternative to AeroShell Grease 17, but when changing from clay-based ASG 17 to Li-complex based ASG 33MS, the normal rules on grease changing should be applied.
