    I don't know how long the tip would last, they seem to burn quickly.

    Thank you for the hint.

    air p.s.i. lowered ? and torch to surface distance increased ? amperage?

    I'm going to try this next time, beats gouging it out, would be good on small collar.

    Easier and safer than anything else I've tryed and it doesn't scar the $$ shaft. Gotta be on the lookout for grease fires though

    Cut off the outer race with whatever, then cut the inner race almost through in a few spots and it will pop off. I have also used a cutting torch, and a plasma to scarf off the race. Once the inner race get good and hot in one spot it will generally come off easily. Want to work fast so as to not put too much heat into the spindle/shaft.

    bearing puller with heat will help, keep heating and cooling to get it unfrozen. a hammer to the race, with heat and the bearing puller should shock it loose.

    So, What happened?

    Did the bearings get pulled, cut, project bailed on, or what?

    are there too many zeros?

    As others said a picture would help and a 2500.00 bearing is something to show.

    Is it possible you could use a slice wheel and cut short of all the way through the bearing's race.

    Also could try putting some pentrating oil on the bearing and with a piece of brass against the end of the shaft hit it with an air hammer. I'm thinking the shaft is out of what ever it was in and on the work bench.

    Yea.....a pic would work wonders. How big is the bearing/shaft? $2500 a pop sounds pretty big to me.....If I could I would remove the shaft and use a shop press.....
