Using magnets instead of bearings?

xingu,

The shaft is not hitting the mirror, the mirror is the only contact point the shaft has.

So which is it, does it touch the mirror or not? A contact point is the point where two or more touch and if they touch, it could be said that they are hitting each other.

OK I see what you mean now.
It seems my english fails me here.
In that case you could say 'is hitting' the mirror.
Sorry, my mistake.
Anyhow I hope 'the picture' of this magnetic bearing is clear now.

xingu, thank you for clearing that up.
