Re: What Drivetrain?

The VexPro hex bearings are complete garbage. All the other parts from vex pro are well made, and designed with attention to detail, but the hex bearings are awful. We have an older robot for demonstrations that has a transmission that uses a hex bearing (not on a cantilevered shaft). For 6 years and thousands of cycles in competition and at demonstrations, the original hex bearing worked. Then, we took apart the mechanism for cleaning, and we decided to try out the vex pro hex bearing. After 3 cycles of the arm, the bearing failed completely.
