It has been the same with every original hub I have seen.
So long as the female taper is OK, I am happy with one of those hubs after I use a repair sleeve in it and new end on the housing with V8 rollers. Alternatively, I pack 3 X NU 1010 bearings in each side.

It really is not the hardening process per se', -and some people have the opinion the bearing rollers were designed to flex. While this was something that it could do on a minute scale, that was never the intention of the manufacturer or the Ford engineers.
The proper name for this bearing was the Hyatt helical bearing since it was designed by a guy named Hyatt. The bearing used spring steel wound in a spiral around a carbon steel or cast core to form the roller. The A-1116-C1 Hub drawing that I have (-which BTW is a Kelsey-Hayes originated drawing #: 11456) shows the hub was forged out of E-E steel and heat treated after machining. No matter which way you play it, the spring steel is going to be harder than the hardened forged steel used in the hub. If the bearing was properly lubricated at all times, wear was never to be an issue for neither the bearing nor the hub race.
