I looked through your catalog, your stock roller is 1"() x 0.25" (7mm). I need any roller mechanism with a 22-23mm outer diameter and 8.5-10mm thickness/width. I attached a photo of what I have with the current dimensions noted in the photo itself.
My cabinet door will not stay in the track with the current rollers, so it's pretty useless.
I don't care what it is made for, so long as I can attach it with a screw. It can be U grooved (as for a door) or solid (as for a drawer). The diameter and width are the relevant factors. Internal diameter does not matter, hardware is easier to find.
