I am doing my first bearing repack. Here are few pictures of bearing and race.

There is some discolouration inside the bearing.
Can I continue using it?
Unfortunately during this season we won’t travel a lot, probably around 1,000 miles.

I hope it will be safe to tow it this year and I will replace these next year.

Looking at the second pic there is a slight "blue ring" but nothing I'd get excited over. Super clean the bear and re pack it. Don't over tighten it.

The roller next to your finger appears to have a problem. Maybe just grease but I can't tell by the photo. If that is just grease, I see nothing wrong. You would do well to clean them better then work completely clean and inspect them again.

“Blue ring” is just a light, the picture isn’t so great.
This is a grease next to my finger.

But I am more concerned with the internal part of the bearing. Take a look first picture, see how dirty/discolouration inside the bearing. Can you see the kind of brown color inside?

The inside looks like it might of moved a little on the axle. If it does not fit snug you might want to peen the shaft a little.
Years ago I learned to first clean and inspect the races, inside of hub. If the race is bad, no point in cleaning the bearing. Replace or not, the inside of hub needs cleaned. Once you have determined the race is good, then clean and inspect bearing.
BTW, I will not judge a bearing good just looking at a picture, can only see about a third of each roller.

It got hot at some point. Clean them up perfectly and examine them with an eyeloupe.

The problem with bearings that have been hot, is that it can mess up the heat treatment and make soft.

I saw this too, right next to his thumb. Hopefully grease. I used compressed air to blow out all of the old grease that will come out, then wash them in a container with mineral spirits. I have a real nice Graymills parts washer but it need a complete refill and that has become too expensive, so I just buy mineral spirits at Wal-Mart in the paint section (cheaper than Home Depot or Lowes) and use that. Once I have managed to swish all the grease out of the bearing (technically a "cone"), I blow it dry (don't spin it) and if it and the race (technically a "cup") are good, then I repack it.
