[TowerTalk] Thrust bearing / rotor load

[WA3GIN]

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.
