Thats not the inner bearing race stuck at the end of the axle ,Its the inner bearing that has come apart .The inner and outter race should still be in the hub.The race s will have to be removed from the hub and changed as well.I would try a little heat with a propane torch and then carefully try to slide it off but be carefull not to damage the threads at the end of the axle.It should not take a lot of heat to expand the metal ring from the bearing.If you need a hand I work in Mississauga .Just shoot me a P.M and I will stop by.Dan
