i need hepl with wheel bearing
is it possible that new hub bearings can have micro flat spots on them to cause the wheel to feel notchy while spinning them?from aset of brand new suzue hubs, i took the bearings out (loose type) cleaned them, then tested them one by one by rolling them on a glass table, i noted they rolled all eratic, if i upgrade to grade 25 bearings could this solve my quest for smoothness while spinning the wheel?

Death fork? Naaaah!!
At first blush, I'd say that the cones are too tight, especially since you state that you had the hub apart. Loosen one side a touch and see what happens.

There should only be detectable freeplay in a hub if it is a QR axle. There is a fine line between tight and slop-free. If it is too loose you can do more harm than you might think by allowing the balls to dent on impacts(I've repaired a lot of those from rough riders).
The balls being 'non-round' is not unheard of from a factory. It is just a lot rarer than it used to be. Another concern that is overlooked oftentimes is the preload on the bearings out of the box is going to be way tight. That is from the quality control department of the factory, when they test for the afore mentioned. The problem arises when the preload is not relieved before a QR is tightened.
Inspect your bearing races and cones. If they are intact, you got off cheap and go treat yourself to some new bearing balls. They are cheap. Put in some good automotive wheel grease while your'e at it(Valvoline 614 is always my fav).

if you're talking about suzue jr track hubs, they're... basic. they'll feel crunchy at first and wear into feeling smoother, but never campy smooth. my personal preference is to run them a little tight until they wear in. also keep in mind the LH and RH cones and bearings are different on these.
