I'll bet they are self-aligning bearings, held to the shaft with eccentric locking collars. If the shaft is a few thousandths under nominal size, the action of the eccentric locking collars being engaged with the bearing, and locked to the shaft will "cock" the bearing a bit on the shaft, and it will wobble as you describe.

If this is the case, if the shaft is not badly worn under the bearings, for the speed at which the PTO runs, and the average hours of use, likely it will go for YEARS without trouble.

It doesn't look good, and it's not desirable, but none the less, it may be "normal".
