Wear rates and friction of plastics

[es_shoes]

I am looking to replace a set of brass and steel sleeve and cylinder having a ceramic tip with a plastic sleeve and cylinder having a plastic tip. The only question I have actually has two parts... are there any plastic, machineable materials that have comparable wear rates to that of ceramic? The probe enclosed on this setup works off the Eddy current, so the tip can't be metal. Just wondering if anything pops out at you guys for a strong plastic with good wear rates, and low friction between two layers of that material. Thanks in advance.

ign plastics such as Delrin and Nylon are commonly used for applications with high wear resistance, low friction, and the ability to be machined. PTFE (Teflon) is another option that has excellent wear resistance and low friction, although it is more difficult to machine. Depending on your application, you may want to look into some of the newer engineered plastics, such as ultra-high molecular weight polyethylene (UHMWPE) or polyphenylene sulfide (PPS). These materials have excellent wear resistance, good strength, and can be machined.
