The IGUS linear motion systems are made for smooth, silent and vibration free motion, at high speed - exactly what you want in your 3D printer. The rods have an extra smooth and hard coated surface.

The rods and bushings in the sets are a 1:1 replacement for the rods and bearings of the Prusa i3 MK3 - no other changes or modifications needed.

The IDE IGUS sets for the Prusa i3 MK4 contains the high speed motion system for the X and Y axis, since the Z axis moves slow, it is not required there.

*product pictures show the MK3S, but the set is for the MK4
