Thanks for reaching out to us! I am familiar with this roller. The one in your photos appears to be missing its outer housing; it may likely still be installed in the door. So you will need to remove it to get a full scope of the measurements from your existing hardware.
All that said, we do not carry an exact replacement match for your existing rollers but we do have a replacement solution that could possibly work.
Start with taking a look at our 81-278 Patio Roller Assembly made with a 1-1/2" Steel Ball Bearing Wheel. To confirm if this would be a fit for your repairs. Again, you'll want to double check the door and remove the outer housing so that you can accurately compare the dimensions.
