· For shaft diameters from 10 - 65mm
· High torsional stiffness, compensation of shaft misalignment at low restoring forces
· Radial assembly! Due to the split hub design shafts can be mounted and adjusted before the assembly of the coupling
· Perfect bellows coupling for servo drives, e.g. in testing equipment, automation techniques, packing machines
· Torque range: 18 - 500Nm
