A good way to remove a bad race that you cant get off a spindle is as
follows:

Dismantle the bearing as far as possible, remove cage etc to expose the inner
race.
With a dremel tool or similar grinder, cut a groove across the race.
Take a cold chisel and hammer and give the race a good whack in the groove.
The race will crack across the groove and spring open a little and from then
on it will be a piece of cake to remove.

The steels that bearings are made of are very hard and consequently brittle.
Cutting a groove across a race creates a weak spot and provides a place for
the chisel to bite.
