sliding window roller

Hello,

Unfortunately, we do not carry a replacement for the window roller shown in your photos. We've related a few similar options on this page for you to review but I can't guarantee that any of them would work since they are not an exact match to your part. Review the dimensions shown on our product pages and see what you think. 

I'm sorry that we won't be able to offer more assistance with this repair but please let us know if you have any other hardware questions. Thanks for posting.
