Weird aluminum balcony door sliding roller

Question

Hello, im trying to update the roller on my doors and im wondering if you guys recognize this roller. Its kind of made for quick replacement. Inside the door tere is small rail where the top part of roller is hooked up and it cant be replaced(seen on picture). But the bottom par with the actual wheel is really easy to replace. It just needs to be turn for 180 degrees and you can detached it.
Im looking for a week almost this part and i cant find anything similar to it.
Are you guys able to help me with it? thank you!

Perhaps I can be of help! Take a look at the 81-004 roller which has a 3/4" thick housing and the 81-023 with the 11/16" thinner housing. Measure the thickness of your existing housing along with the height to see if one of these rollers could fit your door. You will need to remove the bottom rail on the door to drill and counter sink a hole for the mounting screw 33-103. Take a look and see if it is possible. You might want to talk to a professional to see if they can do the work.
