AeroTough GF® (ATGF)® is a proprietary self-lubricating polymer. We design and manufacture grease-free bearing components out of ATGF®. AeroTough® GF bushings can reduce your maintenance costs drastically. Lubrication is built into the polymer formulation, so no grease or oil is ever required for their operation. Corrosion is therefore eliminated and non-existent.
Our formulation for AeroTough® GF includes molecules that provide built-in lubrication and a low coefficient of friction. AeroTough is easily machined, so it's a perfect material to use in making bushings and bearings.
AeroTough® GF polymer parts are only 1/7 of the weight of equivalent bronze or steel parts. The lower weight provides energy savings through reduced fuel consumption. Contamination of the environment with grease or oil is eliminated. Engine carbon emissions are reduced through improved energy efficiency.
Blaine Field, President of Brant Aero, a one-stop service for almost every GA aircraft type and avionics manufacturer, shares his experiences with Marsh Brothers innovative grease-free products. Blaine explains why Marsh Brothers grease-free bearings and seals are a worthwhile investment for aircraft owners, providing a safer operation, and less maintenance costs in the long run.
