Linear shaft is done on the basis of accumulative technology main for the tolerance of outer diameter, linear degree, circ

Linear solid shaft is made of Gcr15 SUJ-2 high carbon steel, with hardness above60HRC, SF plus hard chrome plated layer. For further details and special questions,please consult with our engineer for detailed information.

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.
