Here's another one:

Amazon also has them... If you like Amazon.

I have had one of these up on 3 different towers at 3 locations. Been up for 30 years with heavy masts and TH6/7 and 2 element 40. Both on R25 and R45.

Still works perfectly.

Subject: [TowerTalk] thrust bearings

Greetings All,
I have used Rohn TB3 thrust bearings in the past without issue but I have seen my fair share of worn out  bearings due mainly to an antenna being parked in one direction for a long time- pitted races were the result. I've no experience with anything else and that brings me to my question. Is there something better out there? DXE claims an improvement over the Rohn bearing but it looks as all they did was add a lower seal. I'm leery of Yaesu if the bearings are made from the same pot metal as their rotor mast clamps. Bearing recommendations for an installation with a 2" mast  with about 8' above the bearing and 2' below and an antenna along the lines of JK's C3S antenna are sought.
Tnx es 73,JimW5QM
