These windows are from 1988. Roller is about 9/16" diameter.

The part in the pic is already broken.

Here is part detail.

If you can't get it wondering if their is an alternative to this

The last one's I got on Amazon is super poor quality.

Blomberg windows is no longer around so I'm looking for an alternative.

Thanks, Alec

Hello,

The sliding window roller shown in your diagram looks like a dead ringer for the 87-186 but the dimensions differ from yours. I would recommend looking for an intact roller to confirm if our part could work as a replacement. Take a look and see what you think.
