    Default The bearing supplier will have a bearing heater

    I see the plates go to 400F or so but am not finding any info on "the Google".

    The bearing has some sort of plastic cage...
    The supplier of bearings should have the correct tool for this, properly made heaters are available if you have use for one.

    it has to be kept in mind that the tempering/annealing prozess is temp. and time dependent. there might be no effect of heating to 200° for a few seconds, but dont leave it there for 30 min. (→induction heater).

    I"ve had good luck by heating the bearing with a heat gun and shrinking the shaft with the cold generated from spraying the dustless computer spray can upside down. the spray immediately drops the temp to below freezing and the technique seems to work ok if the bearing is heated a little.
