since only washers hold the bearings on IFI wheels in, once there were bent it was free to fall off at the most convenient time

we built a practice robot last year that used the same wheels, and though we did not have that problem, we didn't like that setup either. Our solution was to insert the bearings in the opposite direction (with the bearing flange inside the body of the wheel) and put spacers between the bearings - this way the bearings can't come out of their hole in the wheel because each one holds the other in place via the spacer(s).
