This, coupled with a bottom support bearing (thing:19313) and a flexible motor shaft coupling (thing:29879) allow you to fully support the weight of the X-axis on bearings at the bottom of the printer without over-constraining the Z-axis, instead of hanging all that weight of the X-axis from the Z motor shafts as in the standard Prusa design.
