Old roller is Leigh brand 3/4 inch wheels. Getting hard to find, no luck at Lowes or two local hardware stores. Found these Swisco replacements on a Google search.
One of my solutions beside replacing rollers was to relocate them closer to door edge. If these don't hold up my next repair will be to replace track with newer type with 7/8 wheels and trim bottom of doors.

Thanks Kathleen, I have used

I think they will be fine.
