Hollow Shaft PS

Materials: SUJ-2 (high-carbon chromium steel)
Hardness: HRC higher than 60
Roughness: 1.5S(Rmax)
*PCS:（PS+ hard chromium coating）

Hollow shaft: For characteristic of hollow structure, the hollow shaft reduces equipment weight to a great extent and simplifies the structure. The internal structure of hollow shaft is suitable for crossing measurement wire, compressed air, adding lubricating oil and hydraulic oil, or used for arm of robot.
