The Andymark bearing went up $1 to $6, but the Vex bearing is the same price as before, $5.
I imagine the failure has something to do with the torsional load seen in 1678's flexible intake arms. Our intake this year had similar flexibility, and when it deformed our intake roller stalled more easily due to the load on the bearings. In a WCD, the load is almost entirely radial, since the double bearing arrangement takes up the torques from the cantilevered wheel and the chain.
EDIT: What Frank said.
