the proper use of a US Tower TX-455 Thrust Bearing Model number TB-2US. I'm
using a 3 el SteppIR on a 5 foot mast. When I tighten the thrust bearing
clockwise it locks itself into place.
Yep, it's eccentric and that's the theory. It's not really capable of
taking much of a vertical load - it's meant more for lateral thrust which it
does okay at.

from on top of the rotor, or do I let the rotor take the full weight. My
rotor is a new M2 (the 90 mph windstorm took out my Yaesu G-800DXA). Any
other suggestions would be greatly appreciated.
The manufacturer wants the weight of the mast and antennas ON the rotator so
don't worry about the vertical load in the TB.
