r PSB could allow for some sort of contra-magnetic bearing system where
the large bearing is a magnetic field instead of a mechanical bearing. I
get your point though, and there is always going to be something to
replace. If not a bearing, then a magnetic coupler for the mag bearings.

There is always going to be some component to break.
