Aluminum door rollers

I just removed these rollers from my aluminum sliding door. I don't see a good match from your photos. They are held in place in the door by a roll pin. The rollers are 1" OD in their groove. They fit into a slot that is 1/2" wide. The axle is a 1/4" roll pin. If you don't have a match for the roller assembly, I could just replace the roller.

Thanks,
Jason
