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.

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.
