I've never found any clear explanation of how thrust bearings are
practically implemented.
If the bearing is to "hold up" the antenna (so that the rotator doesn't
have to), I assume that it's the force from the four radially-oriented
bolts that do so? It seems to me that over time the mast would slip.
Is that really not an issue with sufficient bolt torque?
It seems to me that the mast should be pinned through the bearing
instead--that is, a through-bolt that goes through holes drilled in the
mast.
What obvious (but not to me) thing am I missing?
Thanks,
