Hello Mark,

I'm the one that wrote that knowledgebase bearing post. Further down in the article it was a comment including one of the original pics of a failed bearing that I took apart. All parts are in that pic.

The bearing assembly includes a single bearing, 2 bushings(spacers), and two seals. Pressed through the center of the bearing, bushings, and seal, is a tube wiht a round or hex center depending if you have a round or hex shaft.

All of this is pressed inside the large exteral tube that you see when you look at the disk.

Thanks...but you are saying the just one bearing is in the exact middle...there must be a lot of air space between the bearing and the outside seals....hence why needed a crosssection picture...there isn't one in my disk book either....Thanks for trying to help...Mark

The way I read it mark isn’t asking the fix. He’s asking what’s in the original bearing.

You're correct Mark. There is just one bearing in the middle. Some of that "air" space is filled by those bushings. The little that was left I don't know if it was all filled wiht the seal or what. It's been awile, but in the picture the seal looks pretty thick.
I filled up my air space wiht the felt seal and rubbed greas into it.
