Advanced Synthetic Aircraft & Wheel Bearing Grease MFG Part Numbers: 550067096 (14 oz. Tube) | 550043633 (6.6 lb Can) | 550043616 (37.4 lb Pail) | 550043620 (55 Gal Drum) Operating Temperature Range: -65°C to +204°C (-85°F to +400°F) AeroShell Grease 22 is a versatile, high-performance general-purpose aviation grease formulated with a synthetic hydrocarbon base oil and Microgel inorganic thickener. Fortified with premium anti-wear, anti-corrosion, and oxidation-inhibiting additives, it provides long retention and superior shear stability under severe operational loads. Primary Applications Wheel Bearings & Landing Gear: Engineered for severe high-speed, heavy-load wheel bearing assemblies and landing gear linkages. Airframe Components: Ideal for control systems, actuator screw-jacks, servo mechanisms, static joints, and hinge pins. Helicopters & Accessories: Recommended for helicopter rotor bearings, electric motors, magnetos, and aircraft instrument bearings. Features & Technical Benefits Extreme Temperature Range: Outstanding fluid mobility at -65°C combined with non-melting thermal resistance up to +204°C. Water Washout Resistance: Highly resistant to water leaching and atmospheric moisture, preventing bearing wash-off and rust formation. Synthetic Hydrocarbon Base: Extends relubrication intervals and minimizes load-induced mechanical wear. Specifications & Military Approvals US Military Approved: MIL-PRF-81322 & DOD-G-24508A British Defence Standard: DEF STAN 91-52 French Aerospace Approved: DCSEA 395/A NATO Code: G-395 Joint Service Designation: XG-293 Compatibility Note: AeroShell Grease 22 utilizes synthetic hydrocarbon base oil. Verify seal elastomer compatibility prior to application.
