For my curiosity, can you explain the reason behind this? Is it something to do with a larger shaft/bore surface area to spread the load over, or more rolling elements in the bearing, or something else?

Thanks,

I imagine it has a lot to do with maintenance as well. The wheel, shaft, and spacers are all one part now. Not to mention, it looks incredible.

This is so cool.

Re: pic: 8WD LARGE BORE BEARING WHEEL SYSTEM
I'm curious why you decided to make the end of the shaft bore a hemisphere as opposed to a flat-ish end.
