"Axle" for patio door roller/wheel

A home owner from Vancouver, BC, Canada says:
Sorry I don't know the terminology, but here goes. The patio door is very old, and I can't get replacement roller parts. I'm thinking I'll just drill a 1/4" hole through the door bottom rail, and install one of your wheels (1 1/2" diameter, 1/4" hole). I don't care about having to adjust the height, I'll set the wheel at the needed height. What I need is an "axle". From my searching Google, I think I need a 1 1/4" binder post and screw, to fit your 1/4' roller hole. Do you have that? Thanks, Jay

Can you send pictures of what the roller looks like or what under the door looks like, even the manufacturer of the door?

Hi Dave,
Thanks for the response. Attached are some pictures but it's too awkward to remove the door unless I have a fix for it. I have no idea of the manufacturer, make, model, etc. It's aluminum, very heavy (but only single glazing), and needs new rollers.
The two Track pics are front and behind the door. You can see the scrape marks from the door movement. The 'Roller housing' pics show the adjustable center part of the housing, the roller bearing is completely seized, and the subsequent wear on the brass housing is plainly visible. Although I found a replacement for this part, it's condition isn't much better, and the outer frame of the housing is now broken, and I'm not prepared or experienced enough to dismantle the bottom frame of the door to remove or replace the whole housing/roller.
Finally, my sketch (not to scale) of a cross section of the bottom frame, showing my proposed "fix". Plan to drill through both sides of the frame and insert a bolt or binding post (Chicago pin?) to hold the roller in place.
I suspect said binder post might not be strong enough, so maybe a bolt/nut for the axle?
Your turn....

81-304 would be the axle to use with 81-225 wheel. The picture you sent is the inside part of a wheel assembly. I think it would save you time and aggravation by replacing the complete housing.
