HELICAL Coupling

HELICAL Coupling - Set Screw Type



The HC Series uses high-strength duralumin (AL 7075-6T) to provide excellent torsional rigidity and good tolerance for misalignment and end play. The surface is anodized to provide excellent corrosion resistance and is mainly used for X-Y Robots, medical devices, winding machines, optical devices, measuring instruments, etc.
