Rev-X Bearing Removal

Ok, you mechanics out there. I could use some help please. I have a pair of Rev-X wheels that I'm trying to replace the bearings. Problem is, I can't seem to budge the old ones let alone remove them. It appears they are just pressed in without a holding mechanism. Tried beating the axel out without success. Any help would be appreciated.

Many thanks...Rouler

Nevermind...I was being too gentle. Just have to use more force and drive the things out. By the way, I've heard such terrible things about these wheels, but they've been bulletproof for me for a lot of years.
