Shopsmith 10E 10ER Speed Changer Oilite Bearings.  You get 1 set of 2 bearings. 

These bearings are impossible to find.  You end up having to find something close and having it machined.  I got lucky and found bearings of the correct inside and outside diameters and length.  The flange has been machined to the right thickness.

As I mentioned these bearings are getting hard to find.  They come packed in a hard plastic tube that will last for a long time.  If you think you may need them in the future I would buy them now and hold on to them.
