Can you service a turret bearing?

[alwayskaos]

So I have a used heavy duty turret bearing and was wondering if anyone knows if you can service these. I can't see anywhere how it might come apart, but it makes a little noise when spinning. Can you service these and is there a way to disassemble? Thanks!!

A picture of the bearing would help. I'm not sure if all the bearings are the same.
The earlier black bearings have a round plug / seal in the inside surface of the bearing ring. Slightly larger then the ball bearings inside.
In order to separate the two halves of bearing you needed to remove all the balls.

The Correct answer is ,,,, Maybe. you would likely want to wash the old grease out and put new in and if it is a sealed bearing that comes with complications like the seals.

Top and bottom look the same with no noticeable harware anywhere

Find TM 9-2320-280-20-3 Volume 3 then find section 11-113, Page 11-158

It describes the maintenance. I copied the page. Note the first step includes "Discard Seals" meaning you'll need new seals. I'd try to find them before continuing.

So it looks like no grease or lubricant at all. Remove seal, clean, and install new seal. Seems like it should have some sort of grease in there. There is one small counter sunk screw visible. It looks like maybe the ball bearings are installed thru the hole one by one, whick then locks the two halves together.

Possibly some dri slide or something, but I can see preventing the talcum powder desert dust from sticking.

You found the opening.!!
Yes the ball bearings hold the ring halves together.
You are correct no grease.
Maybe some powdered graphite but nothing wet or sticky.

Thank you!! Seems like its not really necessary to disassemble if it doesn't need grease. Dry graphite it is!!

If I remember the ball bearings aren't steel. Some kind of composite. It's been a long time since I had one apart. I believe it's possible that they can develop a flat spot so separating the ring and inspecting them isn't a bad idea if you have time. Especially if it's not already bolted in place and then has all kinds of stuff bolted too it
