Features and benefits
Advanced wheel bearing protection
Specially designed for aircraft wheel bearings, offering superior protection and performance under high loads.
High mechanical stability
Retains its consistency and effectiveness even under severe operating conditions, reducing the need for frequent reapplication.
Enhanced corrosion resistance
Provides outstanding protection against rust and corrosion, even in harsh environmental conditions, extending component life.
Excellent water washout resistance
Remains effective in wet conditions, preventing lubricant loss and ensuring continued protection.
Superior load-carrying capability
Formulated to handle high-pressure environments, reducing wear on critical components.
Exceeds industry-leading standards
AeroShell Grease 58 is the first grease to exceed SAE AMS3058 standards, as the future for landing gear greases.

Applications
AeroShell Grease 58 has been developed to exceed the requirements of the SAE AMS 3058 Wide Temperature Range Lithium Complex Aircraft Wheel Bearing Grease specification. It is recommended for use wherever severe operating conditions are encountered as in high bearing loads, high speeds, wide operating temperature range, and particularly where long grease retention and high resistance to water washout and corrosive fluids are required. AeroShell Grease 58 is the latest member of the AeroShell Lithium Complex Grease portfolio which includes AeroShell Greases 33 and 64.
The wide range of applications include aircraft wheel bearings, engine accessories, control systems, actuators, screw-jacks, servo mechanisms and electric motors, helicopter rotor bearings, instruments, airframe lubrication, hinge pins, static joints, landing gears.
