I have used a G clamp to stop the disc from rotating. Then used a large screwdrive with a square shaft and a spanner on that shaft.

This is what I meant. Dont tighten the clamp to much just enough to stop it from turning.
Then use circlip pliers to remove circlip.
Then the bearing and the shaft will just pull out.
the bearing will press off the shaft. You can use a vice as a press if you dont have one.

The part number over here for the bearing is SKF 6001-RSH.
