I missed the illustration.
The description of the ball bearing sounds like a primarily radial bearing.
The ball type wheel bearing is designed for significant thrust load as well as radial. (Other ball bearings are designed for only/full thrust load, kingpin thrust bearings for example.)
My 05 VW car has ball type bearings at all 4 wheels. I believe (but not sure) that the "unit bearing" front hubs on most if not all modern pickups are also ball bearings.
Not sure the perspective above is actually comparing the bearings in question.
