Hi Bill,
Why use a thrust bearing at all?
Most rotors can carry several hundred pounds of dead weight
which helps keep their bearings in their races. If a single
thrust bearing is used at the top of the tower and it is tightened
to carry the weight of the mast and antennas, then the side load
actually increases on the rotor, increasing wear on the races in
the rotor. NOT a good plan.
