YAESU GS-065 Thrust Bearing. Fits masts from 1.5" to 2.5" Texas Towers lists them for $59 plus UPS. I'll sell this new one for $45 plus shipping. It is in the box with all hardware and instruction sh
I know this doesn't apply in this situation, but for those mounting a Yaesu GS-065 on a Rohn top plate, R&L sells an adapter that lets you bolt the Yaesu TB to the Rohn top plate with no drilling. An
Does anybody know what size balls are in the Yaesu GS-065 thrust bearing? My cheap caliper isn't precise enough. Looks like 3/8". They're rusted and bumpy. Has anyone had experience with ceramic ball
Ceramic balls have an issue, they really really don't like jarring loads. Their failure mode is to break, vs rust -- 73 de KG2V Charlie _______________________________________________ _______________
McMaster has balls in stainless, 304, 316, and 440. 316 isn't the hardest but is the most corrosion resistant. They are what I use for rotator rebuilds. If you meant "cratered" which happens when the
I think I've mentioned it before on this forum, but I converted my TB-3 thrust bearings over to thrust bushings by machining them to accept inserts made from a dry lubricant-loaded composite, Nylatro
Exactly what I'd do if I needed to rebuild a thrust bearing, unless I could get some free torlon or vespel (haha, I'm funny, those are crazy expensive and overkill) Low rotation rate, shock loaded, o
I have a tb-3 that has been in the air for almost 30 years now, has outlived several rotors, a bunch of antennas, and a set of guy wires... and I haven't looked at it since I put it up there... it ju
Hi Dave, The big difference IMO is that you *use* yours. The really damaged ones I've seen - and they are the ones I inherited to make my modified ones - are from something like a TH-6 mounted on a H

Thanks, Grant - MM-C is the goto place for sure. I just need the size. I meant to type crufted. Autocorrect changed it. We used the word cruft in my programming shop to mean junk. If code was crufted
Thanks George. My TB3 got converted to scrap. Not by me. 73, Mike _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@cont
Plastic thrust bearings are the way to go. Black UHMW is another great (and cheaper) material. Both UHMW or Nylon are UV susceptible but if black or GSM they should last a long time. I recently disas
I used to work in shock and vibration analysis (I ran a lab) one of the classic stories is what Ford found out RE shipping cars. The HARDEST thing on wheel bearings turns out to be shipping cars on t

I'm always amazed at how threads wander off the original question. And by how much I learn from that. Thanks gents. Also kinda amazed no one knows the diameter of the bearing balls. 73, Mike NF4L ___

Bearings to my recollection are mostly metric in dimension. There are specialty inch sized bearings. You have to know what you have to know what you have. JIM WD8QBQ ~~~~~~~~~~~~~~~~~~~~~~~~~
I cannot imagine Yaesu using Imperial units. They could be 10mm ball bearings. Thrust bearing are not that expensive, why not replace the whole unit? John KK9A -- 73 de KG2V Charlie by how bearing? M
