remove bearings, clean off side, read what is printed on them.
Go to your nearest bearing and drive supplier and have him spec a better one for you.

SKF is good stuff. Make sure ya get a SEALED bearing instead of a SHIELDED one.

You do not need to take the saw apart to find bearing number. Grizzly lists the generic number for the bearing also in their parts list. In this case the number is 6203-2RS. It can be ordered from any of the venders already stated. I usually use VBX bearings but they all have good products if you buy the sealed units.

The only bearings I have ever used is Timmkin (sold under Koyo name now), or Bower/BCA…

I was a transmission mech. in the 70s-80s never had a problem.

My G1023 also has that very slight wobble at shutdown I’m sure I’ll be replacing my arbor bearings too. Searching Google I am finding that the 6203-2RS has different thicknesses. I saw 1/2” and I saw 17mm ones. I also found this chart that explains bearing nomenclature. http://www.gizmology.net/bearings.htm

40×17x12 is what I used NTN bearings, very good bearing I checked a few other bearings and this by far was the best one very tight feeling bearing no play whatsoever the KOYO bearings are junk compared to this bearing IMHO

I would go ceramic bearing if I was in a more production shop but they are quite expensive cheapest I could find $63.00 per bearing

Its a shame the Koyos are junk, Timkins were nice in the old days…

I am curious about the country of origin of the Koyos, If they move that bad they are garbage…

But I’m wondering if the one they showed you was one of the series that allows misalignment of the shafts for some applications…

I seem to remember something about a model they carried like that…

I looked in there .pdf file (months ago) and I admit it was a nightmare…

Sorry for the poor advice, but as of now I’m not recommending Koyo anymore…

Glad to hear you have good ones now.
