I am considering using delrin as a linear bearing. It would be drill rod maybe 1" diameter, with delrin bored to something like 1.001". I have machined delrin a lot, but never used it for anything except leadnuts.
THis would be a reasonably high speed application, moving probably about 350 inches per minute max. Are there any other materials i should consider before going through with this? Or is gold old delrin #1?
