Versatile Mechanical Seal

The EA560 is self-adjusting to shaft misalignments and deflections because of the loosely inserted seal face as well as the ability of the bellows to stretch and tighten. The length of the contact area of the bellows with the shaft is an optimum compromise between ease of assembly (less friction) and sufficient adhesive force for torque transmission.
Additionally the seal fulfills very specific leakage requirements.
Because the sliding parts are made in-house, a wide variety of special needs can be accommodated.


  • Single seal
  • Loosely inserted seal face provides selfadjusting capability
  • In-house manufactured sliding parts
