Thanks. I think that LV or needle bearings would not work on this small size. I appreciate the advice against using brass and bronze together. I think I'll go with a delrin sleeve and brass shaft.

Don't do that. Delrin is not strong enough (Pmax = 1000), IMHO.

I would suggest trying a steel or SS shaft and oil/PTFE impregnated
bronze. Follow the bronze bearing recommendations on the hardness of
the shaft Rb 85+ or whatever it is. Test it at higher than expected
loads. SAE863 (oilite+) is stronger than 841 (Pmax 4,000 vs 2,000)
