A part which supports rocker arm, in addition to acting as a hydraulic supply passage for an automobile engine drive control valve system.
High qualities: micro level of preciseness for outer diameter and roundness, surface roughness of Rz1.6 ~ 3.2, cleanness, and for some products are granted with airtightness after both ends are caped.
Since rock shafts for highly efficient engines are multiple tube structured due to its complicated control systems, not only the material is filled with manufactures knowledge but also our accumulated knowledge is also reflected.
