1950s sliding glass door rollers

Your roller does seem somewhat familiar to me, but I can't quite place it. I can at least tell you that we don't have anything in our inventory that matches. Take a look at the rollers and axle kits I've listed for you on this page. I'm wondering if you can use a roller like the 81-156 with the mounting tabs at the bottom of the housing. Also look at the 81-278 single roller, which can be installed from the top down using a machine screw like the 33-103 or up from the bottom. Lastly, we carry wheels and axle kits if you can reuse your existing housing, such as the 81-266.
