I changed one pulley bearing with SKF 6302-2RS-C3 and the other that has a Nachi 6302-2NSE-C3. The Nachi interior race is somewhat broader and you may not will need the washer, but I utilized just one anyhow. I purchased two unique bearings simply to see which a single lasts longer. https://cbpsdirectory.com/listings696455/5-simple-statements-about-roseville-explained
