HELICAL Coupling



HELICAL Coupling - Clamping Screw Type



The HC Series is manufactured with two beams spirally twisted in a cylindrical material to provide soft elasticity in the direction of the axis length. It has excellent torsional rigidity, low moment of inertia, and excellent responsiveness. It is a coupling suitable for servo motors, stepping motors, encoders, etc. that require high speed and high response.

Ordering Instructions

  • Please specify the series, outer diameter, and bore size when placing your order.


  • If keyway machining (on the bore) is required, ensure to indicate this separately.


  • For assistance in selecting the right couplings, please contact our customer service center.

Standard Bore Diameter


※ Bore machining is available within the product’s minimum to maximum bore range beyond the standard bore sizes. (Refer to the figures on the right)
