that looks much better. Thought you had some bad electrolyse going on.
If you can feel a groove in the shaft, there bad, in my opinion.
You need a hardened shaft for a roller bearing on the shaft.

I prefer a bushing instead of a roller. Roller tip! just not roller shaft.
If the roller bearing is still good then just get a hardened shaft to go with them.
You need to do this before you install B3RE KIT.
If he tells you different! listen to his recommendations.
Nowone is responding at the moment. So i just gave you my 2 cents:)
