Sliding aluminum window roller

A quick learner from Camarillo, CA says:

The roller is on the right in the photos. As you can see it is tiny. It is a wheel about 5/16" in diameter with short axel protruding slightly over 1/16" on each side. On the left is a plastic place holder. The assembly is held in place by a 1 inch screw which also serves to hold the window frame together. The window uses 2 rollers, one at each end on the bottom. These windows were installed about 1970 in Camarillo, California.

Thanks for your help.

We don't sell this exact roller, but our 87-212 is very similar in design. It has the same 5/16" wheel, too, though I'm not sure about the size of the housing. Look this product over and see what you think.
