A friend of mine asked Rohn about the tb3 and tb4 bearings. I had a
pair of TB-4 bearings on my old tower setup. I now use peer brand
bearings on the USt HDX-689..with locking collars.

Hi,
I have a question about the TB3 and TB4 thrust bearings. The bearings
are shipped dry but there is no instruction regarding lubrication. Should
these bearings be lubricated, either grease or oil or left unlubricated, or it
is left to the owners discretion? What is Rohn's instruction here?
Thanks,
XXXX

It is up to the user whether they want to use lubricant or not. We do
not feel that it is necessary. We have some that have been installed at
our location for a number of years without lubricant, with no issues.
Thanks,
