Rotor Bearings and Seals

I'm not sure if I'm just not getting it but my 74 Valiant rotor bearings dont look proper. In this picture you can see there is no rollers or anything on this bearing. I thought the bearing had just fallen apart but no pieces came out with it and the other rotor is the same. The new bearings I bought are not similar.

Also, do these seals just hammer out from the top?
