It's a total tolerance of .0005. the acceptable sizes range from 1.125 to 1.1245 for a R8 bearing press fit. +0 just meant no bigger than the nominal size of the bearing.

This is (relatively) easily done via circular interpolation on a quality closed loop CNC mill (this is what we do), or via reamer or boring head on a manual/CNC vertical mill in good condition/proper alignment.
