Take a look at our 23-154 and 23-155 rollers. Both have a concave wheel similar to yours, but you will need to check their dimensions to confirm that they match.

It looks backset like 23-056. 23-056 is not concave, but the backset is similar. I guess the rollers Dave suggested might work if you screw them to the opposite side of the door and simulate the backset depending on the thickness of your door.
