replacement pocket door roller

A home owner from ft lauderdale fl says:
I have searched high and low for a replacement for this 3 enclosed roller for pocket doors. Houses were built in the early 50's. Not a tract home but custom built.

Scale is 1 inch. No markings on any of the hardware.

Are they available anywhere?

Thank you for your patience in this matter. I do not believe you will be able to replace this roller. Your best bet would be to replace the complete track with a new kit, which will come with new rollers.

We are actually currently working on a new track kit. I will post again in this thread as soon as I have more information available for you to view.
