The most recent technological invention of DEUBLIN, which is named "AutoSense" and for which a patent is pending, combines the perfect features of the well-proven “Pop-off” models with those of “controlled leakage”.
The "AutoSense" Rotating Unions provide an answer to the flexibility required today in the range of machine tools or processing centres. The "AutoSense" professional seals close as soon as pressure is applied by a coolant. They pop off, when the pressure of the coolant drops and thereby allow unlimited dry run without wearing of the seal faces
As in case of controlled leakage, they further form a microscopic gap between the seal faces in order to lead pneumatics. "AutoSense" Rotating Unions can therefore lead coolants, MQL and compressed air by sensing the type of medium and automatically adjusting the correct position of the seal.
The series 1114 Rotating Unions are available either in rotor or bore supported design, which – in addition to the “AutoSense” technology for automatic change of the position of the seal faces depending on the medium - feature further characteristics increasing the life time. These include, among others, an optimised flow which prevents depositing of chips and dirt, a protection of the bearings manufacturers by labyrinth und leakage bore holes as well as highly resistant seal pairs which are mechanically balanced and made of silicon carbide for longevity under demanding conditions. ...
