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:   https://www.arraysolutions.com/Products/thrustbearing.htm
Anyway, what say you ?


thanks,
Bob
