Applications
AeroShell Grease 33 has established itself as the answer to most airframer鈥檚 general-purpose airframe greasing requirements, being approved for use in Airbus, Boeing and many other aircraft types.
It sets the standard with exceptional anti-corrosion and anti-wear performance while allowing aircraft operators to shrink their grease inventory and reduce the risk of misapplication. However, there remains a small number of highly loaded, sliding applications on the airframe where the additional boost of molybdenum disulphide will always be required.
To address this need, Shell Aviation has developed AeroShell Grease 64. Sharing the same advanced grease technology as AeroShell Grease 33, AeroShell Grease 64 also possesses the extreme pressure (EP) characteristics provided by molybdenum disulphide.
