Fatigue limits for his bearing were very poor, not a bearing suited for an engine.

But what about the Installation or Pre-Qualification ?
For example - CH bearings are brittle compared to steel and therefore vulnerable to Installation mistakes.
Maybe the CH bearing was also knock-off like some NSK reputedly may have been ? - There is way more to this than just bearing specs.
