Old bypass sliding closet door rollers

A handy person from Los Gatos says:

I'm trying to fix my old sliding bypass closet doors from the 70's that is extremely hard to slide now. They only have a top track with these sorts of wheels. Do you have replacements I can buy to make them slide smoothly again? Thanks.
