A good example of a Thrust bearing is in the drive system of an automobile,
where a bearing is thrust against the clutch plate to disengage the engine
from the gearbox, this is a thrust bearing. The bearing that we use on an
antenna mast is just a bearing that is usually used to support horizontal
shaft that needs to rotate, no thrust involved.

I wonder how the ball bearings know the difference between vertical and
horizontal loads and all the points between?
Boys up here usually run two thrust bearings so they can remove the rotor
for maintenance without having to perform magic to keep things from getting
complicated.
Always fun to read the various post on this reflector.
