I Changed 1 pulley bearing with SKF 6302-2RS-C3 and another that has a Nachi 6302-2NSE-C3. The Nachi inner race is a tiny bit wider and you may not have to have the washer, but I used 1 anyways. I purchased two various bearings only to see which 1 lasts more https://luxepointbrowsandbeauty.com/contact.html
