The magnets that actually turn the fan are on the outside edge that joins all the blade tips together in a circle. They don't ever actually touch anything. The center point seems to be the "magnetic tip." But I can't confirm that without unscrewing stuff. I'm sorry, I really don't want to do that. :)
Anyway, the bearing type is specifically listed as being "Magnetic Tip Driven". If it were anything else it would be listed as "sealed", "ball", (both), or "sleeve". There's absolutely none of that. Plus the fan is advertised as "bearingless."
