Slider glide for wood screen doors, manufacturer JT Windows (closed)

Hi Swisco,
My wood screen doors are being painted. And the glide fell out. It has never worked really well and seeing how rusted it is I now know why. I would like to buy a better quality product. Would a metal wheel be better or a better material for the housing. You have a large selection and your recommendation for a solution would be appreciated.
Thank you,
Monica

fyi - the unit with the slider door was installed 15 years ago.
