The wear collar get replaced with the seal. You can see it laying above the dead blow and below the snap ring pliers in the pic. Its about 2"s in diameter and provides the seal a sacrificial surface to ride on.I would replace both bearings, and with non-Chinese bearings, if you can get them. Personally, I only put cheap bearings in light load, low use, easy to service uses.
If you have a real groove cut, you may want to sand out the groove as a few imperfections can trash a seal pretty quickly. You could try to find an oversized seal. (I have never had much luck trying to do that, but it might be a lucky size.) If it is really bad, a good machinist could spray weld new metal on and get it back to size.
All the best,
