Re: Needle Bearings for Drivetrain

Thanks for the input, all. I'll continue doing some looking into these. It sounds like bushings, of both the Igus and bronze variety, might be worth a shot.

Before anyone asks, though, don't expect to see 751 with plastic bushings and custom 2.5" wheels. We're still trying to get WCD up and running, we're not ready to play around too much with the base design yet (and doing custom wheels wouldn't be fun without CNC. Rotary table time! Hmm, this merits thought...) This is purely a personal project for fun, and is currently entirely theoretical. If I've got time this summer, I'll see about putting together some prototypes to submit to the team. I'll try to get a CAD together in the next couple of days.

Could I use a flanged bushing instead of having a thrust washer or bearing?
