Looks like some hellacious stress risers on the edges of the grooves. I wonder how durable they are, especially in heavily-loaded applications?

I was thinking the same thing. I imagine these would be for fairly lightly loaded applications where reduced friction trumps longevity. I would think that the ball bearings would wear more with this design, just by simply having more surface area in contact with the "race grooves" (not sure what they would be called here).

Hopefully they are amazingly durable and work perfectly as shown...These could cut out a ton of friction if distributed throughout a vehicle (wheel bearings, carrier bearings, transmission tail housings, etc, etc...).

I think they position the groove in a non-load bearing arc.

I wonder how they compare to ordinary non-caged bicycle wheel bearings? It looks like a mod that would be relatively easy to retrofit to a bicycle hub... except I think it would have to be done on the cone and then the cone would need to be indexed relative to the ground.
