Aerospace bushings
Aerospace bushings are small parts under a large stack of demands: temperature, load, vibration, friction, wear, tight tolerance, and limited lubrication. Dominion machines polyimide and metal bushings to those drawings.
Where these bushings live
Typical drawings include aircraft engines, compressor assemblies, variable stator vane systems, actuation, flight controls, pumps, valves, hydraulics, fuel-system hardware, and engine externals.
What we do not invent
We do not claim platform qualifications you have not specified. Send the drawing, material spec, and quality requirements. We manufacture to that contract.
Questions engineers ask
Short answers
Are polyimide bushings used on aircraft?
Yes. NASA technical literature documents self-lubricating polymer composite bearings in aircraft control surfaces and bushings associated with variable stator vanes in jet-engine compressors. DuPont identifies polyimide components for aircraft-engine bushings, bearings, thrust washers, and wear pads.
