Roller Assembly

I'm afraid I can't identify what roller you have from these photos alone. What you're showing me here is just the internal portion of a complete roller assembly. The outer housing appears to be missing; it's presumably still in the door. In order to identify a match, I'll need to see a picture of the entire assembly put together as one unit. 

As for the seal, I'll need you to remove a sample and show me a clear shot of the end profile. The video below will explain what I mean.
