What would cause my barely used green bearing to do this?

I got them from drdiff, but I don't remember exactly what specs or don't have the order form from it since I think I did it all as a guest user. It was a few years ago also, otherwise I'd ask him. They were basically big bolt pattern upgrade axles. I certainly don't want to blame him or any company really until I know what I'm dealing with measurements wise. Maybe something is off more than it should be.

Send them pics and ask what they think could have caused it .
