Bearings are meant to rotate about the lubricated
balls.  If they start to slip or rotate in their press
fit, either because it's been lubed or is loose, the
metal to metal slip will quickly overheat from
friction, burn off any trace grease, and wear, gall or
otherwise damage one metal surface or the other. 
Usually the cast iron takes the abuse, being the
softer metal.  This allows you the pleasure of buying
the entire housing as well as another bearing.  This
holds true whether talking about production machinery
or automobiles.
