What you have there is a separation between the steel sleeve and the aluminum case. If the sleeve hasn’t spun in the case, you should be OK. I would heat up the case in the oven to the point where the bearing drops into the pocket, then let it cool and check if the the gap has closed up. If all looks good with the bearing in place, you should be good to go. Always heat the case to remove or install the bearings, they should fall out or drop in. :-))
If the gap is still there, I would send the case to someone like Swedetech for a sleeve replacement.
