Securing a Oillite bearing isn't easy if the hole isn't correct to begin with. Is the hole for the bearing as deep or deeper than the bearing? Sometimes you can get away with removing the bearing and reinstall with locktite, but keep in mind the bearing surface is impregnated with oil. You may have to re-bore the hole and install another bearing.
If a re-bore to a slightly larger hole isn't in the cards then you might be able to get away with removing and using a small strip of 400 grade black sandpaper to shim the bearing in the hole. Of course if the shaft is too large to begin with, this won't matter much as the whole bearing will rotate in it's holder if not secured properly. Another though, quick and dirty but I would use the idea before sanding the shaft that is to grab a rod slightly smaller than the bearing hole and place a piece of fine grade sand paper around it to enlarge the bearing hole a few thousands.
