new roller for lower track

A handy person from Altamonte Springs, FL says:
I have an old set of Stanley bifold closet mirror doors. They are in good shape, but, need a new roller for the lower track. It keeps binding when opening. Hope you have some ideas. Also, the label pictured is the only thing on the doors as an identifier.
Looking forward to hearing from you.
