ETP-CLASSIC is used in a large variety of applications, for mounting timing belt pulleys, cam curves and arms etc. Positioning along and around the shaft is easy and fast with high precision. Service and maintenance are also easier because of the easy dismantling. ETP-CLASSIC is recommended for all normal needs.


ETP-CLASSIC consists of a double-walled hardened steel sleeve filled with a specially adopted pressure medium, sealing ring, piston, pressure flange and clamping screws.


When tightening the screws the sleeve expands uniformly against hub and shaft and creates a rigid joint. When loosening the screws the sleeve returns to its original measurements and can easily be dismantled



The unique hydraulic principle gives a great number of advantages:

  • Small built-in dimensions and a reasonable surface pressure means small outside diameter for the hub.
  • Mounting and dismantling is fast.
  • Fine adjustment of the hub can be made during mounting.
  • Low tightening torque and a small number of screws makes the mounting easy.
  • Good concentricity also after several mountings.
  • ETP-CLASSIC has cap head screws but screws with hex head are available as accessories.
