PRODUCT

HELICAL Coupling

HELICAL Coupling - Clamping Screw Type



The HCS Series is made of two beams spirally twisted in a SUS-303 cylindrical material to provide soft elasticity in the direction of the shaft length. It is not only resistant to corrosion, but also easily transmits large torque and has far superior performance in response compared to aluminum couplings.


It can transmit up to twice as much torque as aluminum couplings of the same structure. It is a coupling suitable for places that require high-speed, high-response servo motors, stepping motors, etc.

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)
