Also in that gif I'm assuming the orange gear is the spindle, the light green are the ball bearings and the dark green is the cup, correct? Except that in that illustration the green gears are spinning around fixed pins, while in a bearing the balls just roll forward
The cogs in the animation would move in the same way if they were rollers and not attached to a carrier, dependent on friction instead of gear teeth (but note that cartridge bearings have ball cages that act like the planetary carrier in the diagram). Cup/cone/ball bearings are angular contact, which skews the rotational axis of the balls but movement is still basically the same. A deep groove ball bearing as used in a cartridge bearing bottom bracket is not exclusively radial, it also has an element of axial load capacity just like a CCB bottom bracket, albeit less than an angular contact bearing. The deep groove differs from CCB in that the "cup" and outer race are separate parts (unless it's a press fit where the bearing seats directly in the frame).
