Slider window

Hello,

We'd be happy to look into this for you but I don't recognize your sliding window roller at first glance. If you could remove the intact roller from the sash frame to show us a few different angles, along with written-out dimensions, we can go from there. Thank you. 

Thanks for getting back to us. Unfortunately, we do not carry a replacement for the sliding window roller shown in your photos. I'm sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions. Thanks for posting.
