Patio door roller
I'm afraid I wasn't able to find an exact match for this roller. We have a few different varieties that are similar, but they all differ in terms of size.
I would say that the closest option is our 81-046. This has a 1-1/4" wheel, a 1-1/4" housing height, and a 3/4" housing width. Additionally the flares stick out to a total width of 7/8". The major issues with this part is that the height is off from yours slightly, and the flare is oriented much lower than what I see in your photos.
Our 81-289 is the only roller we have in this style whose flare is a little closer to the center, but the dimensions differ much more dramatically with a 1-1/2" diameter wheel and 1-1/2" housing height. I would wager this is too big to consider.
Ultimately I think the 81-046 is our best option, but due to the stated differences I cannot guarantee that it will work for you. I suggest looking it over yourself to see what you think.
