One way to tackle something like this would be to drill, bore, and possibly ream the end of the shaft to take a standard hardened and ground dowel pin. Press the pin into the shaft, leaving enough sticking out to serve as a precision "stub shaft". Then use a small, cheap needle bearing to support the dowel.
