I Changed one pulley bearing with SKF 6302-2RS-C3 and one other using a Nachi 6302-2NSE-C3. The Nachi internal race is a tad broader and you might not want the washer, but I utilised a single in any case. I bought two various bearings simply to see which just one lasts https://luxepointbrowsandbeauty.com/contact.html
