[TowerTalk] Replacement Thrust Bearing

[Doug Renwick]

Get a Timken/Fafnir YJC series bearing.  They are the best but not cheap.
The don't make a 2" ; the closest is 1 15/16".  If you need something a bit
larger in diameter, I have had machinist mill the inside to fit 2+".

I am overhauling my rotator and thought it would be good to replace my
thrust bearing also.
I have the Rohn TB3 bearing now.  It has been in use for 18 years and feels
pretty rough.
Im thinking of going with a different bearing this time with a steel body
and greased. (grease fitting)  
Looked thru the archives on tower talk to find out what others have used and
can't find much,
on this type of replacement and I know the bearing supply houses have them,
just haven't 
pursued searching with them yet.   I would like to know what others have
used.
If you have used a thrust bearing like this,  could you share 
the number and supplier ?  Array Solutions has their model TB2 which is this
type 
of bearing but it only has a two hole flange for mounting.  They have a
larger unit with a 4 hole 
flange but it is for a larger diameter mast than 2 inch. I want a 4 hole
flange but for 2 inch.
Here is the info from their webpage:

Anyway, what say you ?


thanks,
