DXRH

Our latest rotary axis solution, the DXRH, 1 degree of freedom (DOF) mechanical bearing design, is characterised by exceptional accuracy.

The DXRH is characterised by its encoder system and unrivalled mechanical properties comparable to those of air bearing solutions – without the associated complexity. Supported by HEIDENHAIN best in class encoder and bearing technology and our toothless direct drive motor, the DXRH ensures precise performance without torque ripple.

Full compatibility with our standard interfaces enables seamless integration and performance upgrade without the need for redesign.
