You'll have to do the same thing I had to do. Sears is out of biz, so they only have what they have in stock for parts. If you can find out who made their bearings and contact them, or take the size of it to any place that handles bearings and get a new bearing. I had the plastic dust collector fan on my planer broke I contacted sears to get a new one. They didn't have any and couldn't order one. I took it to a machine shop and had them make it out of alum. I had the same thing happen with my bench top bandsaw. Broke my last bandsaw blade and went to sears to get some more. They no longer carry them and can't order any. They sent me to MDS Blades to get one made. 70-1/2" is a custom order so they wanted $115. per blade. Told them no thanks, I can by a new saw for less then the cost of 3 blades. I went back to sears and made them look and see who made their blades? Contacted them and they had a bunches of them in that length, any TPI you wanted for $8. a blade.
