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.
