The top bearing should hold the vertical load.  I use the rotator bearing to
stabilize the mast vertically. Why do you need a second TB2US?

I'm about to raise a 72' US Tower equipped with a pair of TB2US thrust
bearings 
spaced about 3'.  I'll be using a TailTwister2 Rotator.  Is there a
procedure 
for centering these components to preclude binding?

I doubt there is a way to make the two bearings share the vertical load, so 
which one should I choose.  I'm thinking that the top bearing should take
the 
load and use the lower bearing to stabilize the mast laterally.
