SWISCO - The Replacement Hardware Authority

no name bare aluminum sliding rollers/axles bad

A handy person from Reno, NV says:
Many houses in the Reno, NV area have these unbranded aluminum sliding windows. The rollers and/or axles in most of our house are shot. With some effort I could remove them, they are probably original.

Looks like the axles pull out on one side, or the head of them wears out because it serves as a guide when a nylon guide wears out or breaks. The axles are almost exactly 2cm long. The axles are 4mm in diameter and the wheels are about 16mm in diameter, probably worn a bit appear to be aluminum maybe?

I'd like to replace wheels, axles and the nylon guides as well. Sending two photos of a window that works OK and one where the axle has pulled out and bent and the wheel is not really functional.

The closest wheels I've been able to find with are our 87-192 and 87-193. Take a look and see if you can adapt either to your window. They are not exact, and I can't be sure they will work, but we have not been able to find anything closer.
