In 2004 the National HF 6/4 machine was completely reconditioned, besides replacing the mechanical components used, it was made the complete replacement of the induction heating installation

with a new one; also the original lubrication system TRABON was updated. In the URB bearings plant with this National 6/4 it used toproduce bearing rings, maximum outer diameter 120 mm, for oscillating bearings with balls, radial bearings and tapered rollers bearings, from bar steel 100 Cr6 (Max. diameter of bar is 65 mm), with the maximum weight of 3.1 Kg. Also, on this machine it had been made cardan crosses.
