    Chrome Plated Round Bars

    Chrome plated round bar is mostly designed to be used for hydraulic piston rod and pneumatic piston rod manufacturing and repairing. So some people also may call this product hydraulic cylinder rod approximately.

    However, besides the above, chrome plated rods can also be used in applications where high performance surface finishing and high accuracy dimension tolerance are required.

    Here below is the application list of the chrome rods:

    • Hydraulic cylinders (chrome plated piston rods)
    • Pneumatic cylinders / air cylinders (chrome plated piston rods)
    • Guide rods for plastic manufacturing machine and hydraulic machinery
    • Rollers for machines, such as packing machine rollers, printing machine rollers
    • Shaft for machinery, such as Textile machinery center axle, Transport machinery center axle, etc.
    • Ejector rods for injection molding machines
    • Vibration absorbers and pistons for some industrial machinery.
