need replacement rollers for patio door

What is the make and model of the door roller modules in the attached picture? Can you sell the roller modules to me? The rollers are about 1.25 inch outer diameter. They are from a sliding glass patio door. The building was built about 1982. The doors and windows look like the originals, same as most others in the development. Location is Florence KY. The windows are all aluminum frame. Another picture shows the etched mark on the window glass. The icon may be for the manufacturer, the text is all about the glass specs. Thanks for your help.

Thanks for the part match. It looks like the roller holder I posted a picture of with the carrier frame that is still in the door. On the web site I clicked the button to be notified when the part is back is stock. Thanks again for your help.
