It may be only shallow relief but I haven't heard this happening before. Common sense says that if a bearing fails twice then it's more than likely what ever the bearing is placed in, in your instance the hub.
It's possible that there was a machining fault in the bearing seat in your particular hub, there may have been a lip that hadn't been machined out or too much had been machined out causing movement in the bearing.
I doubt it's a faulty batch of bearings otherwise there'd be a lot more cases of it. And it would be extremely unlikely that you'd get a faulty one in servicing when you consider the likely hood of them being from the same batch. Then again, stranger things have happened.
It will also be telling if more people have the same issue.
Hope I've helped.
