This can also happen after the bearing has been installed where the equipment itself is subject to vibration. A big problem on ships and such where spare motors etc., are stored. It could have been subject to electrical tracking or arcing, especially if any welding has been done near it without taking precautions. As there is only one roller involved you can be pretty sure that it has been stationary when whatever caused it occurred, ruling out lack of lubrication.
Very interesting and logical about the welding. Thanks!
