Bad wheel bearing?!

Well I guess I'm the only one that thought it was strange the way this bearing wore only in one perfectly proportioned spot on the inside race.
The rollers are fine, the outer race is fine, the grease wasn't burnt and smelly...etc
I work on boats and trailers for a living
And have replaced hundreds of wheel bearings
Over 35+ years and never have I seen this type of failure before.
Lots of dead bearings from lack of grease, water intrusion, no maintenance...ect
And they always fall out in pieces or everything is worn evenly.
I like to find out what happened in what I'm working on out of curiosity if nothing else.
I'm still interested after all these years...lol
Got a call into Timken I'll keep you all posted.
Thank you fabo!
