I purchased a Rohn TB3 bearing from Texas Towers which did not turn very
smoothly and often times jammed when turning it by hand. I exchanged it for
a different one (thanks Gerald) which seemed a little better. The new TB3
was still not smooth, but at least it turned without jamming. I installed
it on top of a 70' tower in Aruba and after several months I checked it and
this one also jambs when turning it by hand. The rotor so far has been able
to turn it. On my Rohn 65 tower in Illinios I have a Create bearing on a
3" mast which I am very happy with, unfortunately I don't believe that they
are still available. Is the Rohn bearing junk and is there something better
that will fit a Rohn 55 tower?
