[TowerTalk] Suitable Mast + Thrust bearing

[mohammad almutairi]

Hello again,

How about 1.9" OD   SS 316L Sch 80  Pipe ?

As for the thrust bearing , after seeing it in the shop this morning ,
the general description as written in the the page cataloge is as
follows: Product 121B is a bronze/oil bearing which allows you to use
masts up to 2 3/16" in diameter. The thrust bearing can be bolted to
all high gain crank-up towers if the rotator mounts below the top
plate. 
I have never used a thrust bearing befor , I am not sure if this model
is simmilar to the Hy gain TB3 one. The bearing collar in this one just
sits on top of the bearing flange . I really don't if the others use
ball bearings or not ?
