Glass door roller

Question

This is the bottom of a mirrored rolling door,  possibly as old as the 70's. It isn't staying in anymore and the screw that goes in the top to hold it in is too big for the part itself. Any help would be greatly appreciated. Thank you!

I'm having a hard time making out your roller from these photos. Would it be possible to see the whole thing removed from the door? Not just the inner roller portion but the outer housing, as well. Seeing the whole assembly together in one photo without obstruction will allow us to find a good replacement.
