Jorge, amigo, sorry but I can't recommend a two part bearing to use without
the grand hassle of pulling the mast. You might be able to "surround" your
mast with "rollers." You will need at least 3 rollers (wheels with their own
bearings) arranged at 120 degree intervals.  If it were me, I would go for
two levels of 3 rollers per level to distribute the force such as you would
avoid denting or crushing the mast due to sharply concentrated force at the
contact areas.  I would recommend considering placing a section of
telescopic fitting tubing to strengthen the mast at the points of contacts
with the rollers.  This reinforcement would have to be split into two pieces
to be put onto the mast for the same reason you can't just easily swap out
your failed bearing assembly.

Other that something along the lines of the above, I have no clue how to
avoid the major pain of taking it all apart.

Good luck amigo,
