It’s actually the opposite, since the bearing wear is twice as fast in the single row because of the double load compared to the dual row. So the single row starts pitting much sooner. DOF would make sense if the failure was the result of lack of lubrication. But that’s not the case in a bearing that’s swimming in oil all the time.
