Rollers

From what I can tell this window was made in 2007.  I have attached everything I can find out about the window.  The housing for the roller measures:  1 11/16" x 15/32 x 13/32 and the roller measures 13/32 in diameter, wheel width is 5/32, and total width with axle is 9/32.  If you need any other information I am happy to help if I can. I am looking to replace the roller if possible with either a brass or steel roller. If I need to replace the entire housing as well, that is fine.  Thank you
