ETP-TECHNO consists of a double-walled hardened steel sleeve filled with a pressure medium, and a flange. The flange part contains the pressurizing mechanism, which consists of a screw and piston with double sealing function, an o-ring and a metallic seal with a steel ball, which is pressed against spherical a seating.
The outer and inner diameter and the side of the flange towards the hub are accurately machined for extremely good concentricity.
The pressurizing mechanism is designed for 1000´s of mountings.


When the pressure screw is tightened the double-walled sleeve expands uniformly against the shaft and the hub thus creating a rigid joint. Dismantling of the joint is done by loosening the screw. ETP-TECHNO returns to its original measurements and can easily be dismantled.


  • The unique hydraulic principle gives a great number of advantages:
  • Fast mounting/dismantling. Only one screw needs to be tightened.
  • Extremely good concentricity, also after several mountings.
  • Can be mounted/dismantled 1000´ s of times.
  • Possible to mount in tight spaces. The pressure screw is tightened in the radial direction to the shaft.
  • Small built-in dimensions.
  • The hub can be adjusted easily and accurately.
