Attaching things to ball bearings

[ksquared]

Let us say I have a run of the mill ball bearing (inner ring, outer ring.)  Does anyone know how exactly you are supposed to mount stuff to the inner ring?  And yes, I mean axles, I suppose, but any ideas are welcome.

Thanks alot.

Hi,

Either by a very(!) tight fit, or by clamping it between bushings matching the diameter of the inner ring.
(Glue might help if the fit is less tight).
