AeroTough GF

AeroTough® GF is a proprietary engineered thermoplastic, designed exclusively for aviation applications to replace existing metal bushings, providing a smooth grease-free operation. AeroTough® GF does not require lubrication as it has built-in self-lubricating properties and can also run with typical aviation lubricants. AeroTough® GF offers good dimensional stability in oil and operates through a wide range of temperatures so it can be installed with tighter clearances in applications such as control surfaces and landing gear oleo struts.

AeroTough® GF is a homogeneous self-lubricating polymer, capable of withstanding operating pressures up to 65MPa (9427 psi) installed in a full form, interference-fit bearing configuration. 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 throughout the aviation industry.


  • Excellent wear / abrasion resistance
  • Excellent dry-run performance
  • Low friction, self-lubricating, high pressure – velocity (PV) limit
  • High strength and low creep
  • Excellent chemical resistance to aviation fluids and compounds
  • Good strength retention with increasing service temperature up to 70°C (158°F)
  • Maximum continuous service temperature in oil: 80°C (176°F)
  • Maximum continuous service temperature in air: 110°C (230°F)
