Mast thrust bearing?

[KJ6CYD]

Hi,
I need to make two thrust bearings for an antenna mast. I have two thrust bearings with a 2” id. What I am looking for is an idea or cross section view of how these bearings are retained and bolted to the plate of the tower. Any ideas or links appreciated. I do have a machine shop in my garage so machining these is no problem. Thanks and 73!

I've always used these types of bearings to take the suspended weight off the rotor. You can use a standard rotor plate to mount them on. This link just gives an idea of how the bearing looks. The ones I usually get look like this but cost around $35-40 bucks.

Look at item number: 00598428

I use a flat top rohn tower, so mine just bolts to the top of the tower. If you haave the other type, you will have to buy a plate to put inside your tower above your rotor to support the weight of the antenna and mast.
