[TowerTalk] Thrust Bearing

[Wayne Kline]

Hi... a picture of the TB-3 thrust bearing is in the rohn catalog http://www.radiancorp.com/ROHNNET/rohnnet2001/catalog/pdfs/25G/25G-16.pdf

 

As you can see the bearings (ball are encapsulated  between the top rotating plate and the bottom mounting plate. 

In a LOW RPM and not stored out side in a upright position, will last for a long time. A proven design

A new thrust bearing that has been used lately my Hams is the yaesu GS 065 thrust bearing 1 1/2 to 2 1/2 in OD mast dia.

check them out also..
