I'm curious because I know they're other teams that run WCD's with hex bearings and to my knowledge they don't have any problems.
How exactly were your bearings configured on your WCD? What was your bearing block setup like? How close together were your bearings? Did you do anything very different from the stereotypical WCD in your drivetrain?

Yes. We destroyed probably a half dozen bearings in a non-loaded low speed application. We ended up not using that particular mechanism on the robot. However, the incidents of failure left us with a very low opinion of the current generation of hex-bearings.
Our application was single shaft non-cantilevered (supported by bearings at both ends). The bearings blew out sideways after the races cracked.
