Acorn Dorwal Sliding door Rollers

A home owner from NH says:
Hi, I need to replace the rollers here. Hopefully the photos are helpful in finding the right part? I don't have model number, but the doors are approx 26 years old. Thanks for any help

Take a look at the 81-030 Acorn patio roller. I believe this is a newer version of the one you show in your photo. Just make sure all its dimensions all match up, that's the most important part.
