I don't think the 5202 bears much resemblance to a matched factory pair of 7202 ACBs except in superficial appearance. Certainly not in performance imhe. A good bearing, but for a different application.
Factory pairs of ACBs tend to be a shade more expensive than two stock ACBs. In a production environment the extra cost is not significant. For hobby use you can arrange the preload yourself by carefully doing up the retaining nut. Yes, it can be done by 'feel'. You will need one of those locking washers where you hammer a couple of tines over. Don't try to use a lock nut: that will wreck the preload.
