Like z_beeblebrox was saying, the number varies due to the laser kerf, as well as the softness of the wood. If you haven't tried it before, I would cut a test piece with different sized holes in 0.001" increments to determine the ideal size. The other option is cutting holes slightly too small and sanding the inside until the bearings press fit.
