I think making anything apart from the positioning/retaining "washer" for the rollers out of delrin would actually be
counter productive. You don't want anything sliding against anything else, you actually want things to engage other things and make them roll, just like in a ball bearing - nothing should ever slide inside a ball bearing but instead balls should engage inner and outer races and roll thus producing smooth motion. If sliding occurrs you end up damaging bits and getting less than optimal motion. So forget delrin, this should be all steel.
