Manufacturer's description
Synthetic Grease for Aircraft. AeroShell Grease 7 is an advanced multi-purpose grease, composed of a synthetic oil and clay thickener, possessing good load carrying ability over a wide temperature range. It is inhibited against corrosion and has excellent resistance to water. The useful operating temperature range is –730C to +1210C.
Applications
- AeroShell Grease 7 satisfies nearly all the airframe grease requirements of turbine engined aircraft and also those of piston engined aircraft provided that seal incompatibility does not occur. Most civil aircraft manufacturers approve AeroShell Grease 7 as a general purpose grease either by brand name or by specification. It is recommended for lubricating highly loaded gears, actuator screw mechanisms, etc., also for instrument and general airframe lubrication within the temperature range of –73 0 C to +121 0 C.
Performance & benefits
- AeroShell Grease 7 contains a synthetic ester oil and should not be used in contact with incompatible seal materials
- AeroShell Grease 7 is a clay-based grease approved to MIL-PRF-23827C Type II; it should not be mixed with soap-based greases approved to MIL-PRF-23827C Type I
