They are standard 3/32 ballraces which have an OD of 3/16" or approx 4.76mm.
Basic quality bearings, like the slot.it ones, are easily available i.e. SFR133ZZ Budget Metal Shielded Stainless Steel Flanged Deep Groove Ball Bearing Simply Bearings Ltd (note, I haven't used these or the supplier so it is not a recommendation)
If you want better quality bearings you are probably best looking at part suppliers for BSCRA or ISRA type slot cars.
