It looks to me like the adjustment is / was all out of whack.

The wear marks on the bearings isn't quite where I'd expect to see them



Ideally the bearings should be running in the middle of the cup not kind of on the outer edge as shown in the picture. I'd expect to see them further in a bit.

I guess it was all a bit loose and that's how the clip got worn.
