Rollers and seals
A home owner from California says:

I need replacement rollers and weather seals for aluminum windows from the 60s whose appearance is attached. The roller is a nylon cylindrical wheel about 11.5 mm in diameter (7/16 ") and 5.3 mm thick. The hole is about 3.2 mm. The wheel is held in place and rotates around a nylon "nail" whose rounded head doubles as a bumper to allow the window to slide instead of scrape along the channel. All of the wheel, the "nail" head, and the weather seal have worn down to where the wheel doesn't turn and the head-to-seal thickness no longer keeps the window from rattling.
