AeroShell Grease 5 is a high temperature grease composed of a mineral oil thickened with Microgel®, with good load-carrying ability. It is inhibited against oxidation and corrosion and has excellent resistance to water. The useful operating temperature range is −23 to 177 °C. It is particularly effective as a wheel bearing grease, especially when landing speeds are high, and is suitable for lubricating aircraft and engine accessories operating at high speeds and relatively high temperatures, such as magnetos, generators and starters. For rolling bearings required to start at temperatures as low as −23 °C, an adequate period should be allowed for the grease to channel.
