I bought a stainless steel axle and tested how well it performs in a simple Lego hoist. How much better is it compared to a standard plastic axle?
The axle specs:
Lego Technic compatible
19 Lego-units long
stainless steel
bought from Brick Machine Shop in www.bricklink.com https://store.bricklink.com/Eezo?itemID=106643711
later sold by cncgear in www.ebay.com https://www.ebay.com/itm/19-units-long-stainless-steel-axle-X-style-works-with-Lego-Technic-gears/262583950400
