In rolling friction, exhibited in rolling element bearings, there is still resistance to motion, albeit orders of magnitude smaller than for sliding friction.
If these can be replaced by angular contact ball bearings, manufactured to the original main dimensions in order to guarantee that the mating parts can be used further, it leads to a dramatic decrease of the frictional losses as the sliding friction of the tapered rollers against the shoulder of the cone is replaced by the rolling friction of the balls in the ultra-precise raceway.
