Replacement rollers needed

Question

We are in need of replacements rollers for our sliding doors.  There are no numbers or identifying elements on the door or the rollers.  The rollers are nylon.  Dimensions can be seen in photos.  Hoping you can help us identify a proper replacement.  Thank you.
