Some headsets don't come with the bearing cover, but I can't figure out how they work. I have never actually installed a headset without the cover, but I did have one like that sent to me with a frame I bought. When I told the seller the head set was incomplete, he apologized and sent me another one just like the first one. No cover. I threw them away and bought a complete one. I don't get it.
