AeroTough GF is a proprietary non-metallic material frequently used to replace existing metal bushings to provide smoother grease-free operation. The lubrication is built into the polymer formulation, so no grease or oil is required, eliminating corrosion issues and reducing maintenance costs significantly.
The material, which originates from the self-lubricating bearings developed by the 100-plus year-old parent company Thomson-Gordon Group, is 1/7 the weight of equivalent bronze or steel parts. Capable of withstanding operating pressures up to 65MPa (9427 psi). AeroTough GF was originally formulated for use in landing gear applications but can be used in a wide range of aviation applications including any rotating and oscillatory joints.
