If that's the case, why not just use a caster or something similar? It won't be driven anyway.
An igus bearing will work, though.

Perhaps shoulder bolts will help

This, or, possibly, just a regular bolt. Sounds like you're in a pretty low-stress environment. The main thing I'd just point out is that bearings aren't designed to go over rough terrain, so you might want to avoid off-roading. A bolt and a bearing is probably fine (though a little sketchy) for light use.

I can't really tell from your descriptions and pictures, but are you trying to move something linearly along / inside an extrusion, like an elevator? In these cases, you'll need multiple bearings / bearing surfaces and can accomplish their mounting with two plates and a bolt going through both of them. It's a lot harder to do it inside of a tube compared to the bearings riding on the outside of a tube. Perhaps I'm not understanding you well.
