HELICAL Coupling

HELICAL Coupling

 - Set Screw Short Type



The HC-SS Series is a coupling designed to be short in length. A relief shape is machined on the inner diameter where the helical slit is formed to prevent damage to the coupling due to axial interference caused by eccentricity or misalignment, and the tightening angle of the fixing bolt is 120 degrees to disperse the force fixed to the shaft.

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)
