Hi Perry..
That 2RS means "Sealed both sides..." some bearings have only the seal on one side and the ball bearing retainer,balls are open on one side..
These 2RS bearings can be repacked but require a little gizmo that can be bought at any bearing house that will do the job..but they are so cheap that it is better to just replace them as you can't see the condition of the balls or inner or outer race and only would be done in an emergency situation..
They come from the factory pre greased so as you figured out the seals are already in the bearing..
