If you are bit nervous using the grinder here's a reasonable way of doing it;

With suitable protecion,
Get one of the already mentioned slitting discs (welding suppliers do them)
Cut part way through the stuck race in line with the axis of the axle and bearing race.
Next get an assistant to either support race and axle with something imovable and hard like a dolly on blocks of wood
or
Get them to wedge a hammer underneath it (not the safest of ideas)
Then use a sharp cold chisel in the groove and hit it with another hammer it should shatter, however, if heat has been applied up to cherry red then you may have annealed it so it could take a bit more of a whacking to crack it.

The proper tool is one of these. A bearing splitter. You tighten it behind the bearing and then use a 2 arm puller to heave it off.

A good hire shop should have on the right size.

Quite correct, however, I've seen pullers jump right of at the worst time when you've wound up a right load into them, they also need to be bought and can be quite expensive (usually the best quality that actually work)

Thanks for all the advice guys. I've already tried the pullers, so heat next!
Just need to find a friendly neighbour to nick a heat gun from.

I'll give it a crack at weekend - when I've caught up on sleep.
