You could lubricate using a simple stick of wax. Something like our 75-077 is a popular choice for screen and glass doors.
Otherwise, it sounds like you'll need new rollers and maybe even a new track, depending on how severe the corrosion is. We may be able to help with that, but it's not possible to ID the hardware you have now without first seeing them. That will require taking your door down so that you can remove the roller for a visual inspection. There's no way around that.
Let me know if that's something you want to pursue. We will need a clear picture of the track (you don't have to remove that, at least) and the rollers fully removed and shown without obstruction. From there, I can then check our inventory to see if we have a good match.
