The placement of the cage as in this invention reduces the inertia by reducing {HEAD ~ the radius} at which the cage mass is located and reduces the effect of {TAIL ~ this inertia} by eliminating the back and forth motion of a cage of the prior art construction, i.e. closely adjacent to the outer race
