PEEK is a great resin, way better than nylon and better than Delrin and also much more expensive. However I think there are some newer composite resins like Hydlar which I think is a Kevlar filled nylon that gives both strength and lubricity. The old glass filled nylons had good strength but also caused wear on the shafts they were supporting. (I'm speaking as a plastics guy, not specifically about transmission applications)
Not sure how easy it is to machine or suitable for a pilot bushing.......there is getting to be an awful lot of engineering resins on the market with special purpose fillers in them.
