They are dual 15mm ID deep groove ball bearing supported on the output shaft.
The weak spot in the VP output is the snap ring holding the output shaft in place. For most loading conditions this usually doesn't matter, but with pull out loads generated by lead screws the snap ring can fail due to pull out.
The Industrial versions of these type of gearboxes all have the last stage of the planet carrier integrated into the output shaft so they do not have this same failure mode.
