ZAPEX ZN Gear Coupling

Double-jointed gear coupling
Nominal torque range from TKN = 1,020 Nm up to 162,500 Nm with 12 sizes
Temperature range: from –20 °C to +80 °C

Strong and reliable

ZAPEX ZN® couplings connect machine shafts and compensate for angular and radial misalignment. ZAPEX gear couplings from the ZN series are made of high-quality quenched and tempered steel and are manufactured according to the modular construction system.

Did you know?

The design of the ZAPEX ZN coupling’s hub has been optimized with regard to the maximum capacity of the bore range (up to 288 mm). Due to the smaller and more compact size of the coupling, bearings within the driving and driven machine are less loaded. A long service life of the drive can be ensured.
