Our roller is 1 1/4 inch on the screw side and we tried some that size (from a Home Depot.)and it won't lift the door.
Do you have anything like this roller we have???
We see the Product 81-158 but it is 1 inch instead of 1 1/4 ... don't know if you have anything else. All the other dimensions are correct except for the 1" size one the screw side.

Good morning! Based on your description and photo, I think our 81-166 may be a better match. I recommend carefully reviewing all of our measurements just to ensure it all lines up. Alternate image for 81-166
