The remaining ridge is still quite visible and I am showing the remaining height. I have been in the tool & die business for more than half a century and understand how things are made. If you cannot or will not accept what I have presented, fine. I still have a customer that his entire business is bearing failure, preventive maintenance and lubrication analysis, he is in total agreement with my conclusion. Perhaps you have more expertise than the both of us.
As I said, you could be correct, based on the available evidence. But I've worked around bearings and machined surfaces also for 40 years, and I've seen bearings fail and look just like that. Since I had put the bearings together, I knew they were good from the box. I don't know that I have more expertise, but I know that after the fact analysis doesn't always result in the correct answer. Just the way things go.
We'll just have to agree to disagree.
