Lynn Erickson Posted March 1, 2008 Share Posted March 1, 2008 If my memory serves me correctly Delerin is softer than uhmw. I work at a sugar factory and we use uhmw for bearings in shafts that contact sugar which is very abrasive. It works pretty good. That is what I am using for my bearings. Here is a picture. STeve It is POM or Polyoxymethylene or commonly known as acetal resin or Delrin the Dupont trade name. is is very easy to machine and very stable. it machines very precision and is a good bearing for low speeds. Delrin is much harder and stronger then UHMW. UHMW is a slicker bearing material but is a much softer material. either one will work for our purpose. as does the plans phenolic. the phenolic can be bonded with epoxy resin but the delrin and UHMW can not.
