ZAPEX ZW Gear Coupling

Please enter your complete MLFB number here
(E.g. 2LC0170-4AB11-0AA0)

Strong and reliable

  • Double-jointed gear coupling
  • Nominal torque range from TKN = 1,300 Nm up to 7,200,000 Nm with 31 sizes
  • Temperature range: from –20 °C to +80 °C


The double-jointed gear couplings from the ZAPEX ZW® series compensate for angular, parallel and axial misalignment of shafts. They are particularly suitable for use under rough operating conditions. In addition to the standard series, couplings up to 13,500,000 Nm can be supplied.


Your benefits at a glance

  • Low restoring forces in the case of shaft misalignment
  • Suitable for both directions of rotation (reversing operation) and vertical installation
  • Long service life and minimal maintenance requirements
  • Small dimensions owing to compact design for use in confined spaces
  • Can be used for high shock loads; with large safety reserves
  • Suitable for use in potentially explosive environments; certified according to 2014/34/EU (ATEX)

Did you know?

The teeth of the ZAPEX ZW are lubricated with oil or grease. Special double-lip sealing rings are used to seal the tooth space. These so-called DUO sealing rings offer double security preventing lubricant from escaping and dirt from entering the tooth space. Thanks to this, a long service life of the coupling can be ensured.
