Applications
AeroShell Grease 5 is particularly effective for use as a wheel bearing grease, especially when landing speeds are high, and is suitable for the lubrication of aircraft and engine accessories operating at high speeds and at relatively high temperatures, e.g. magnetos, generators and starters. For the lubrication of rolling bearings which are required to start at temperatures as low as –18°C, an adequate period should be allowed for the grease to channel.
AeroShell Grease 5 is also commonly used on piston aircraft propellers.
