This is a replacement for an Alside 5100 sliding patio door. All of the measurements match except where your diagram shows 1 1/4" I measure closer to 1 1/8". Wheel diameter is 1 1/8". Is the 81-030 the correct replacement? Thanks!

The potential problem with a taller wheel is that you might not be able to clear the bottom of the sliding door track to reinstall your glass door. There is a chance your original wheel has been worn down a bit over the years which would make the 81-030 with the slightly taller wheel a good replacement for you. Take a close look at your roller and try to determine if the roller might have been worn down to a slightly smaller diameter.
