Buying guide

How to choose Rotex

What matters when choosing: properties, comparison and typical applications.

Design and Components

Hub unbored, finish-bored with keyway to DIN 6885/1 or in stainless steel 1.4305.
Spider elastic element in various Shore hardnesses with colour coding.
Jaw geometry transmits torque positively between the two hubs.

Typical Applications

Rotex jaw couplings connect motor and driven machine in a torsionally flexible way, damp shocks and compensate shaft misalignment. Selecting the spider hardness lets the damping and stiffness behaviour be matched to the application.
