Re: FRC Bearing Load Ratings (Climber Winch)

If you use 5mm hex stuff a lot it may be worth investing in a 5mm hex broach (McMaster has them). Some teams have ground their own broaches from old machine tooling for a lower-cost option. (Not that I have anything against filing, if you making just a few it's a great option)

To directly answer your question, I recall seeing a team last year with 3D-printed wheel hubs, so printed parts can be used in high-stress situations. Your success will depend on the printer, materials, and printing pattern, not simply that its 3D printed. You can also do fun things like soaking the part in epoxy to make it ~100% dense and thus stronger.
