Wheel Bearing and Engine Accessory Grease

AEROSHELL Grease 5 is a general aviation grease suitable for wheel bearings and high speed applications including magnetos, generators and starters.

Microgel thickened, mineral oil base

AeroShell Grease 5 combines high load-carrying ability with excellent resistance to water and high temperatures. Aeroshell Grease 5 is inhibited against corrosion and oxidation, and has a useful temperature range of -23C to + 177C. Aeroshell Grease 5 is used primarily in aircraft wheel bearings and engine accessories operating at high speeds and relatively high temperatures.

AeroShell Grease 5 is high temperature aircraft wheel bearing and engine accessory grease. It is made with high viscosity base oil and a Microgel non-melting inorganic thickener, providing excellent load carrying ability and resistance to water washout.
