... that they fail because of structural weakness.
The reason, IMNSHO why they fail sooner than a double-row or the larger single row is because they have less surface area (between the ball and the race) and when the acid in the burnt oil starts to pit the surface it will fail sooner.
The bearing itself is strong enough to sustain all of the loads the engine will subject it to.
The problem, once more is the lack of proper lubrication.
YMMV.
Happy Boxstering,
