This collar is a locking eccentric and it has a hole in the side for a pin
wrench (or whatever) to tighten it. This centers it
automatically in the bearing. Don't throw it away - just make it work. It's a
common way that it is done. It's probably Peer
bearing.

Subject: [TowerTalk] MA550-MARB Question
I have recently received my MA-550 with MARB rotator base from UST. All
arrived in fine condition.
Included with the base bearing is a collar with setscrew. Collar is machined
with an eccentric 'rabbet' (for lack of a better word)
in one of the two flat sides.
The bearing has a mating eccentric machined on it. The shaft of the mast is
not large enough to enable the collar's setscrew to
fix it in position.
The OD of the shaft is 1 1/2", the ID of the bearing is 1 3/4". Not exactly a
sliding fit. Can anyone tell me what's going on
here. Do I just discard the collar and drop the shaft through the bearing and
go? Or is there a bushing or something I'm missing.
I received everything on the Bill of Lading.
Thanks in advance
Gil, W1RG
Naturally it's Saturday. Can't call UST 'til Monday.
