The altitude bearings are PVC endcaps turning on pound-in furniture sliders. The azimuth bearing surface is more pound-in furniture sliders turning on a vinyl record.

Many thanks to frequent commenter David DeLano for advice on sealing and painting the wood, discussions on bearing surfaces, and some peel-and-stick Teflon tape that I ended up not using (too slippery, if you can believe that).
