New from Deublin is a bearingless AutoSense long-stroke rotating union for coolant, MQL and air service. The 1154 Series rotary union features patent pending AutoSense technology that automatically changes between closed seals and controlled leakage in response to the media - be it coolant, MQL or air.

The nonrotating element has a long stroke to track drawbar movement even when the union is mounted on a clamping device.

Balanced mechanical seals made from silicon carbide offer long service life.
