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.
