these are the ceramic bearings or no?
No, they were the stock steel bearings and I'm replacing them with stock, although I considered ceramic from a manufacturer who claims that the Campagnolo bearings are too small. The bearings are much smaller than those in my Nuovo Record cup and spindle BB which I haven't replaced in the 40 years I've owned the bike.
