Anyway, I need one. I used to have one, but sold it. I've searched, but no luck. Hard to find.
Here's a picture.

Thanks, I'll try to dig one up. Should see a resurgence in that stuff with cord cutters gaining popularity.
Amazon shows the TB-105 bearing, but , "currently out of stock." Most places I looked said out of stock or discontinued.
Maybe this one from Yeasu will fit the bill.

They've been out of stock for along time. I needed one for a project about 8 years ago and couldn't find one. Got lucky and found a NOS on ebay. It worked great, but sold it like a dummy. Sorry, but the Yaesu bearing won't work. The UTg105's work great as they allow a higher height above the rotor. Solid Signal doesn't even stock them.

Are you looking to take the vertical load off of the rotator, or lessen the radial deflection that the rotor has to handle ... or both ?? If a mast-mounted thrust bearing is not commercially available, you can make a suitable substitute using a pillow block bearing with a lock collar.
This would absorb all radial deflection, and could provide additional vertical support without suffering damage. Easily mounted to a small metal plate and held to the mast with suitable muffler clamps. Probably not too expensive. Just a thought

I was thinking about just such a bearing. The one you pictured looks like it has set screws to clamp onto the shaft/mast.
Yep, my brain is conjuring up several things. I need some ratings on this and others like it. Might be able to use a few of these and place a rotor at the base to turn the wholeshabang.
I might have a lead on a thrust bearing like I had before. I'd rather have this one. This looks fairly easy to build, though.
