Rotary Union

Check up to five results to perform an action.

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.
