ROTEX® couplings are designed to transmit torque between drive and driven components via
curved jaw hubs and elastomeric elements commonly known as spiders. The combination between
these components provides dampening and accommodation for misalignments. This product is
available in a variety of metals, elastomers and mounting congurations to meet your specic needs.
Ordering Guideline: There are three individual part numbers you will need for a complete
coupler (i.e., 2 Hubs and 1 Spider). Please choose the hub sizes that match the criteria for your
application. In addition to the hubs, you will need to choose a spider, from the spider section.
Customization options are available; allow Anaheim Automation to specify the coupling
designed for your application!

The above misalignment gures for ROTEX® couplings are standard values, taking into account the load of the
coupling up to the rated torque TKN and an operating speed n = 1,800 RPM along with an ambient temperature of +180ºC.
For other operating parameters, please ask for KTR-Norm 20240 on misalignments for ROTEX®. The maximum angular and
parallel misalignments must not be used concurrently. For example; 70% of the maximum parallel value allows 30% of the
maximum angular value. Also, care should be taken to accurately maintain the distance dimension “E”, allowing for axial
clearance of the coupling while in operation. In case of an axial thrust, the dimension “L” must be taken as a minimum
dimension in order to keep the spider free from pressure against the face. Detailed installation instructions are available at
www.ktr.com.
