Bottom rollers for patio door

Question

I need to replace the front and back rollers on a patio door. I do not know the brand of doors. The doors are 20 to 25 years old.
Can you identify the part from the pictures and can I get replacements?

Take a look at our 81-278 and 81-179 rollers. These are the first that come to mind looking at your photos. See if either of these match up to your size of the housing and diameter of the wheel. The dimensions are very important, so I highly recommend you confirm that ours match yours.
