Huco Coupling
The Huco coupling has a 13mm OD. This is multi-beam type 3, aluminium L 168 clamp 4mm x 4mm coupling. This is readily accommodated by any combination of axial motion, angular and parallel misalignment. Its 3 start helical cut design provides higher torque capability and reduced wind-up as compared to single beam versions.
