replacement roller assembly

Thank you for sharing your photos with us. The "D1519" stamp you show in your first photo, can be cross referenced to our 23-232S roller assembly. However, since we do not know your measurements, we can not say for sure if this is the correct part for you. I would start by taking a look at that as well as our 81-269 and 23-080 assemblies. See which of the three is most compatible to your piece.
