Die for pressing in/out small bearings

thingiverse

I made this die to replace some 625ZZ bearings in a PLA bracket, which won't hold up to metal brackets. To get started, place the outer ring against the bracket and the inner plug against the bearing race on the opposite side of the ring. Next, use a vice or, if you're fortunate enough to have one, a press to apply pressure until the bearing is forced out of the bracket into the outer ring. The plug should come loose easily from the bracket.
