The rawlbolt trick is worth a try. Welding a bolt to the remains of the bearing never fails. the heat of the weld will loosen it and the bolt gives you something to pull on. cut 3/4's the way into the race every 1/3's around the circumference and used a small chisel to break the race out.

Do bearings need to break in?

No, not really, but most tapered wheel bearings should be checked for proper adjustment and preload torque after a little initial running time. Sealed bearings, whether ball or roller type, require no break in period. Care must of course be taken that they are properly installed.

What temperature do you heat a bearing?

Hot mounting

Normally a bearing temperature of 80 to 90 °C (144 to 162 °F) above that of the shaft is sufficient for mounting. Never heat a bearing to a temperature greater than 125 °C (257 °F), because the material may change metallurgically and produce alterations in diameter or hardness.

Can you reuse bearing races?

If the race surfaces are completely smooth and free of discoloration (most often caused by heat build up) then you can leave them in place and just replace and re-pack your bearings.
