I just installed my third HAMIV rotor; I got about 4 years each from
the previous two. The most recent failure was the pot, with 5-6 turns
worn through at the spot I usually leave the rotor.

That sure sounds like a short life for a rotator. As you have it inside the
tower (?) I guess that you have a thrust bearing at the top of the tower.
Are you near the salt water or in a very windy place ? Do you contes with
it and turn it a lot ?

I put one up about a year ago that was used,but rebuilt. I am not in an
area that is very hard on the rotators. I hope it will last longer than 4
years. It is in the tower about 5 feet down and I have a thrust bearing at
the top. Just truning a 3 element tribander and beams for 6,2, and 432 on
15 foot booms.
