Review on Bonbo 608ZZ Ball Bearings 8X22X7Mm by Aaron Urena

Each bearing is packed in a sealed bag. I used them to replace two bearings in a Window AC fan motor. Tried four different bearings and the center hole diameter was slightly larger than the original 608Z bearing installed in the fan motor. Unfortunately, the enlarged bore allows the motor shaft to rotate within the bearing without the bearing itself rotating. Bad handling. In addition, each of the bearings rattles during rotation. I'm not sure if there's junk in there. Don't expect them to last very long. You get what you pay for.
