I changed one pulley bearing with SKF 6302-2RS-C3 and the other by using a Nachi 6302-2NSE-C3. The Nachi interior race is a little bit broader and you might not want the washer, but I used a person anyways. I bought two different bearings just to see which 1 lasts extended. https://directorylinks2u.com/listings13166044/considerations-to-know-about-lower-lip-threading-in-west-roseville
