Mechanical Shafts
Saehan’s mechanical shafts have a mechanical structure.

The lug stroke can be moved in the left and right direction of the lug housing using the male and female screw devices embedded in the journal section. Because of the uniform and powerful tightening of the paper core, it is possible to push up the lug by making the lug housing move forward. It can be moved forward by turning the screw using the impact wrench. For recovery, simply turn the screw in the reverse direction using the impact wrench. It is possible to replace a lug as it stops at the lug housing on the circumference of the mechanical shaft.
