I would guess PTFE.

https://en.wikipedia.org/wiki/Polytetrafluoroethylene

Bearings seals[edit]
In industrial applications, owing to its low friction, PTFE is used for plain bearings, gears, slide plates, seals, gaskets, bushings,[40] and more applications with sliding action of parts, where it outperforms acetal and nylon.[41]
Could very well be what's on there. The idea of making them like what's on my Roper is what I'm bringing. Delrin (POM) is another good material to use for the bushings.
