Disc Coupling

Disc Coupling -

Clamping Screw Double Disc Type



The DC-B Type is ideal when there is a difference in the diameter of the shafts to be connected. For example, it is ideal when connecting a large shaft diameter of a servo motor reducer output shaft and a small shaft diameter of a ball screw shaft. The high-elasticity disc is made of stainless steel (SUS 303) and has a long service life.

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)
