I am looking to replace the rollers/roller assembly for an aluminum sliding door. There is a large headed screw or bolt running from inside to outside through the door with a two piece roller assembly inside. There is an octagon shaped cutout on both inside and out outside piece is threaded.

Hi, I would start your search by looking over the 81-230 wheel. It was very popular in the early days of Acorn, but without seeing your roller, I can't confirm this is definitely what you need.
