We have succeeded in refinement of surface texture of shafts by YSK technology of induction hardening treatment. At last high strengthened shaft is born by this texture refinement. It is 1.4 times of rotating strength and 10 times of abrasion resistance strength than conventional shafts. We have substantiated compacting and weight reduction of shafts for press machines and rolling rollers. The refinement shafts solve your problems and respond to a demand, Our technology can make shafts with further strength and further prolong it's life.

Instead of depending on adding alloy elements, we refine crystal grains by using our induction hardening technology and have succeeded increase the strength of steel.
