AeroShell Grease 64
Synthetic Lithium Complex Aircraft Grease with 5% Molybdenum Disulphide
AeroShell Grease 64, formerly known as AeroShell Grease 33MS, is a synthetic aircraft grease designed for highly loaded sliding applications on airframes. It is based on AeroShell Grease 33 and fortified with 5% molybdenum disulphide, also known as MoS2, to provide added extreme pressure protection where a moly aircraft grease is required.
This dark gray lithium complex grease combines the anti-wear and anti-corrosion performance of AeroShell Grease 33 with the load-carrying benefits of a solid lubricant. The result is a practical aviation grease for demanding grease points exposed to sliding motion, high loads, and severe operating conditions.
AeroShell Grease 64 is suitable for applications requiring performance against MIL-G-21164D, NATO Code G-353, and Joint Service Designation XG-276. Always confirm the correct grease selection against the aircraft maintenance manual, component requirements, and approved lubrication documentation.
Key Benefits
- Fortified with 5% molybdenum disulphide for added extreme pressure protection
- Designed for highly loaded sliding airframe applications
- Synthetic lithium complex formula for aviation grease requirements
- Provides anti-wear and anti-corrosion protection
- Useful operating temperature range of -73°C to +121°C
- Formerly known as AeroShell Grease 33MS
- Dark gray color for easy identification
Recommended Applications
AeroShell Grease 64 is intended for aircraft and aerospace grease points where a moly-fortified grease is specified, especially:
- Highly loaded sliding airframe components
- Grease points requiring added extreme pressure protection
- Applications calling for AeroShell Grease 33MS
- Applications referencing MIL-G-21164D, NATO G-353, or XG-276 requirements
- Aircraft maintenance programs where MoS2 grease is specified by approved documentation
Do not use AeroShell Grease 64 as a general-purpose substitute unless the aircraft or component documentation allows it. Molybdenum disulphide greases are typically used where specified.
