Hello!
The roller in your first picture is only the inner housing so I can't be certain what you have. However, the screw tabs in your second picture reminds me of our 81-018. I can't guarantee this is what you need so you'll need to remove a complete roller assembly from the door and compare the dimensions to confirm this matches up.
