The "stub axle" is more properly called a spindle. Was the ridge far enough out that it lined up with the outer edge of the bearing race once it was installed? If so then it belongs there.
I've had bearings seize and they removed metal & made the replacement bearing race loose on the spindle, not the other way around. The only exception was the one that welded itself to the spindle - that was interesting. Also, most don't realize that the original wheel bearings in our Mercedes were made in Japan or China.

There was a ridge next to where the bearing inner race seated. I sanded the ridge as much as I dared with emery cloth but the new bearing would still not go and I didn't want to try and drive it on. I took the new bearing back and got another new bearing, thinking the first one might be off-dimension but it wouldn't go on either. In desperation I went across the street to Autozone, thinking they might have foreign bearing with less precise dimensions, and got a Chinese bearing which went on with no problem. That was about 8 years ago and the Chinese bearing has caused no problems. I've often wondered how that ridge around the stub axle formed. I didn't think high strength steel such as is used in stub axles is malleable/plastic enough for a frozen bearing to create a ridge without it being raised to a temperature up in the 2000 degreeF range. That is pretty much true when working with a forge. High strength steel has to be a dull shade of red before it can be shaped. It would seem that such a temperature would make the stub axle unusable.
