A further thought, for the lower bearing next to the arbor, partial failure of the roller cage might allow one or two of the rollers to skew out of position, resulting in the observed small amount of eccentricity.

Beavers use a pair of angular a pair of contact ball bearings at the bottom and a deep groove ball bearing at the top.

Thanks for better information, I was merely assuming common design practice. That probably means that there is no end float adjustment available. In that case, a fault in the angular contact pair seems possible. I suppose the good news is that replacements will be somewhat cheaper than taper roller bearings, provided they are not unusual imperial sizes.
