It looks like I did find the the item on this website, but wasn't entirely sure if there are different sizes of this model or simple generic one that is utilized for sliding doors that have this particular roller.

Hello,
Unfortunately, there is no generic roller that will work for doors using this style of roller but I would recommend starting with our 84-074 or stainless steel 84-074B and seeing how the dimensions on our product pages compare to yours. Thanks for posting!
