Abody rotors

I'm getting ready to start putting my suspension back together so I'm gonna go ahead and order new rotors. This may be a dumb question but I dont know the answer so...
Do the rotors come with new bearings or do you have to buy them separately? It says in the description rotor and hub assembly. I would think hub assembly would mean in does but Idk. Iv never bought rotors for a abody before lol thanks guys
