Patio door rollers that need replacement

HI

I have uploaded 5 photos of the old rollers that need replacing on an old heavy glass patio door. It looks like part code No. 23-288 may be one that could work. But of course I will wait and see what you recommend to purchase. I also took 2 photos of the roller partly in the channel of the bottom of the frame, but I am only allowed 5 photos. The only thing that holds the roller in is the screw securing the bottom of the frame. There are no other retaining screws for the rollers. But there is a screw on each roller that is an adjusting screw? If you need further information please let me know.

Thank you very much.
