I agree with the request/focus on bearing ratings, but I'd be less concerned about bearings on a simply-supported climber shaft failing than I would a wheel bearing, particularly in a WCD-type application. The climber shaft should see very low (if any?) dynamic loading, where-as the drivetrain bearings will often see a wide variety of dynamic loadings... even if the climber never falls and the robot lands on its wheels. ;-) Additionally, the drivetrain bearings experience a lot more cycles/use given that they're used almost continuously during the match and are often turning at higher speeds.
Regardless, it'd be good to use more than experience from other applications!

I'm curious if teams are going to be getting themselves into trouble with bearing loads on their climber winches....
