Greetings All,
I have used Rohn TB3 thrust bearings in the past without issue but I have seen 
my fair share of worn out  bearings due mainly to an antenna being parked in 
one direction for a long time- pitted races were the result. I've no experience 
with anything else and that brings me to my question. Is there something better 
out there? DXE claims an improvement over the Rohn bearing but it looks as all 
they did was add a lower seal. I'm leery of Yaesu if the bearings are made from 
the same pot metal as their rotor mast clamps. Bearing recommendations for an 
installation with a 2" mast  with about 8' above the bearing and 2' below and 
an antenna along the lines of JK's C3S antenna are sought.
Tnx es 73,JimW5QM
