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...).
