Re: Swerve drive questions

If you go to the Igus web site they have info on using AL anodized shafts for use with their sleeve bearings. Igus supports First and we have used their bearing and anodized shafts many times. Make sure you find read and understand their comments on sticktion with plastic bearings. Chrome coatings tend to delamenate- flake off with point contact loads. Hard anodizing works.
You don't have to use the ball thrust bearing on the transfer shaft but if you want a low friction durable solution use them. Let the thrust bearing handle the axial loads and the ball bearing handle the radial loads. We have looked at that vertical many times and keep going back to steel and needle bearings.
