Great answer Scott. I would just like to add with some rotators such as a K7NV Prop Pitch, it is recommended to have the full weight on the rotator.

Probably one or the other, not both. That's "overconstrained", which
means anything just slightly out of true can produce very large forces.
The easiest way is usually to let the rotator take the vertical load,
assuming it is within its rating.

Installing a thrust bearing in a tower - Dead weight (along the gravity
vector) all on the rotator or all on the thrust bearing?  Seeing such things
as sleeves for towers, I would surmise that all of the dead weight is on the
rotator and only off-axis loads (perpendicular to the gravity vector)  are
handled by the thrust bearing.  I use two thrust bearings in my tower which
I don't believe effects the answer to the above question.  Ken K5RG
