· Backlash-free metal bellows coupling with clamp hubs
· Hub material: aluminum
· Alternatively to steel executions we recommend our series KB4AL from size 80 - 500
· For shaft diameters from 10 - 70mm
· High torsional stiffness, compensation of shaft misalignment at low restoring forces
· Easy assembly and low inertia
· Perfect bellows coupling for connecting servo motors, e.g. in machine tools, automation techniques, packing machines, wood working machines
· Torque range: 80 - 500Nm
