Patio Door Roller

This is a very unique roller. I don't think we'll be able to find an exact match. That said, see our 81-237 nylon roller. The diameter is 1-11/16", which is a little larger than yours, but I'm hoping you have an adjustment on the housing that can make up for that. I would also compare the thickness. The 81-237 is 3/8" thick and 1/2" with the hub. Also see out 81-310 roller axle repair kit.
