The bearings are sealed at both sides, if it weren't sealed on
the outside, road dirt would get in, it wouldn't last!
The outer seal is probably behind the inner race that stayed on your
hub when you pushed it out.
I wouldn't use liquid nitrogen, you could damage the seals when in a
frozen state, during assembly.
