I ask because a 50% "bad" figure is so far from what I've been able to glean that I'm wondering how there could be such a difference in our figures.
The statistical failure of this bearing can reasonably be set by the manufacture of the original bearing. When NSK made this bearing it was stated that it had a life to failure rating of B10. B10 is a failure rating in that infers that 10 percent of the bearing will fail at that load and whatever number of cycles that it is based on.

So the safe number to say how many of these bearing will fail is 10%. Lucky me, after having mine analyzed, it is in the earliest of stages of failure.
