GERWAH® HS, HD and HC: The advantages of the system

1. No tooth backlash

  • An important property for synchronous operation or for machines that are frequently used in start/stop or reverse operation. GERWAH® couplings are ideally suited to applications in which the positioning accuracy of the control system in both directions is important.
  • 2. Torsional stiffness

  • The design of the coupling guarantees a high level of torsional stiffness, which is an important property for applications in packaging machines, servomotors drives, printing presses and machine tools.
  • 3. High temperatures

  • GERWAH® couplings can be used under extreme temperature conditions up to 240 °C/460 °F, e.g. in high-temperature fluid pumps.
  • 4. High speeds

  • Due to the very strict production tolerances, GERWAH® allows precise vertical alignment and a high level of true running accuracy, making it ideal for applications involving high speeds even with irregular rotary forces.
  • 5. High service life

  • The highly accurate disc pack insures optimum force distribution, while its flexibility also protects against vibrations from the drive. GERWAH® couplings do not wear, so that a long service life is guaranteed
  • 6. Maintenance-free operation

  • GERWAH® couplings are maintenance-free and do not require greasing or cleaning
  • Characteristics
    Mounting with key GERWAH® HS, HD, HC

    Multiple-disc coupling for compensating of axial and angular misalignments.
    Versions with 2 disc packs can also be used to compensate for radial misalignments.

    • High torsional stiffness
    • High transmissible torques
    • Can be used up to temperatures of approx. 240 °C/460 °F
    • Maintenance-free operation
    • Attachment of the coupling to the shafts with keys

    Non-standard spacers
    Many applications for GERWAH® couplings require special spacer lengths and dimensions. We can supply spacers with lengths of up to 5m.

    Higher rotational speeds and/or special couplings
    A coupling sometimes needs to fulfil certain industrial safety standards or is operated at very high rotational speeds. We can also provide solutions for this.
