Just FYI, I'm in process of renewing all the rollers and fittings on the sliding glass doors and their screens, on a standard 1962 Lucas Valley Eichler house. And I'm finding all the parts I need at www - wgsonline - com, at fairly reasonable prices. Another company, www - doorandwindowparts - com, has all the same bits with higher prices but cheaper shipping. The source company for all those bits, www prime-line-products com, is good for research and particularly helpful "how-to" advice.
As an experiment, I refurbished one screen door with nylon rollers and another with steel rollers. The nylon ones are MUCH quieter, though probably wouldn't last as long.
Finally, I bought a roll of JVCC polyethylene film tape, 1/2 inch wide, on Amazon. This is "slippery" tape, sometimes used for drawers and anything else you want to make slide easily. I put it across the top edges of the screen doors, so they'll slide in their tracks without any aluminum-aluminum scraping.
Results so far: excellent. Price has been reasonable. One word of caution: the tall glass doors are really heavy. Get someone to help, or at least to spot you, when you take them out and put them back in.
