• Rotating Air Tubes

    Air tube assemblies are used with all rotating MicroCentric air chucks. The rotary air coupling features a hardened steel journal and a mainte nance free oil-lite bearing.

    Rotary air tubes include a blank support bushing, air hoses and fittings. Length to be specified when ordering. Contact our sales department for assistance in determining the correct length for your application.

  • Non Rotating Air Tubes

    MicroCentric's patented NR50 air tube is used with HST/HS chucks. This air tube couples to a rotary air journal mounted in the ID HST/HS chucks. The NR50 is a three passage design for coolant through the spindle or automatic lubrication.

    NR50 air tubes include air hoses and fittings. A support bushing is required to fix the tube to the rear of the machine spindle. Contact our sales department for additional information.

  • Rotary Union

    A rotary union is required to supply coolant through the air tube assembly, or for the AL-Automatic Lubrication option. Rotary unions can be mounted to the rear of LDZ Air Cylinders to supply coolant or air through the machine spindle to the workholding fixture.

    The rotary union threads into the rear of the air tube and includes a hose and fittings.
