Wheel bearing and engine accessory grease. Composition: Microgel-thickened mineral oil base. Combines high load carrying ability with excellent resistance to water and high temperatures. It is inhibited against corrosion and oxidation, and has a useful temperature range of -10°F (-23°C) to +350°F (+177°C). Used primarily in aircraft wheel bearings and engine accessories operating at high speeds and relatively high temperatures. This grease is increasingly being used in high temperature industrial applications as well, such as drying ovens. Qualified under former MIL-G-3545C (Obs) specification.
