You need to be mindful that as the bearing comes back up ambient temperature, water will condense on it. You will have to dry and oil it immediately to stop it flash rusting.
Remember that metal gets brittle at extremely low temperatures. I'd limit use to the dry ice.
Only time I was ever around liquid nitrogen was when we was artificially inseminating cattle .
It kept the " Bull juice " cool until the rite time .

Bevel gear shaft and bearing here. We haven't got the the finals yet but I'm sure we're eventually headed there :/.Never did use liquid nitrogen for bearing installation but imagine it would cool a Barley Soda down quick .
De burr & clean up the bore good and we just use old school race driver punch on everything .

I don't know if putting hot oil on a very cold part is a good idea. Once the part thaws out would be better.
