Roha-D couplings are torsionally rigid all steel flexible couplings suitable for highly precision drives where a backlash-free shaft connection is required. These couplings transmit torque reliably even in the case of very high speeds and compensate for axial, angular, and radial misalignments. They are suitable for temperatures up to 250°C, and are ideal for synchronous input and output especially in NC and CNC drives. These couplings are approved by German Lloyd for marine applications.
