Could also be that the bearing was already replaced and that is why it got staked in. If it was replaced it may have been replaced by a cheap substitute and that's why it failed again. I have seen so many bearings fail, this didn't used to be a problem but with all of the junk on the market today it is a common occurrence now. I also see many bearings that have NO lubrication in them even though they are brand new. I always try to inject some oil or grease now so the bearing has *some* chance at a long life. As Rich says, they even counterfeit the packaging. Your best chance is to find a NOS bearing if you can.
