RS,

I’m not certain how much help I can be but I can tell you how I found bearings for my planer. I took the old bearing to an auto parts store and they told me what it was. They wanted 4 times as much as I could buy it online, so I looked online until I found what I needed. In doing so, I became (slightly) more educated on bearings and figured out how to interpret their codes. That was a couple of years ago and I can’t now remember all that I learned, but I did find that they are generally measured in mm and in all three dimensions (thickness, i.d. and o.d.). Different companies have difficult codes for a smooth interior. I think mine were coded ZZ which I think is smooth inside and out.

If you go to a site like this, you can click on a few links and learn more about how to find a correct replacement.

Wishing you success!
