These are disc-spring couplings that use a lightweight, high-strength aluminum alloy for the clamp hub to enable high torsional stiffness and high response. Both single-element types with high torsional stiffness and flexible double-element types that separate double elements with a spacer are available. Both lower the moment of inertia by linking the outer diameter of the hub to the shaft diameter.

* Check the Standard Bore Diameter list as rated torque may be restricted by the holding power of the shaft connection component.
* Max. rotation speed does not take into account dynamic balance.
* Torsional stiffness values given are measured values for the element alone.
* The moment of inertia and mass are measured for the maximum bore diameter.
Features of SFC Models
These are disc-spring couplings that use a lightweight, high-strength aluminum alloy for the clamp hub to enable high torsional stiffness and high response. Both single-element types with high torsional stiffness and flexible double-element types that separate double elements with a spacer are available. Both lower the moment of inertia by linking the outer diameter of the hub to the shaft diameter.
Ultra-low inertia
The outer diameter shape of the clamp hub is linked to the bore diameter you are using. This decreases inertia to the lowest amount necessary by reducing the outer diameter when the bore diameter is small, making these optimal for fast-accelerating operation. Three shapes are available to match the combination of bore diameters you are using.
Simple, reliable, no backlash
Since the clamp method is used to couple to the shaft, mounting can be completed by tightening one bolt each on left and right. Clamp hubs enable reliable connections that are strong against vibration and shocks, and all power is transmitted by frictional couplings, so there is no backlash. The clamp hubs on both sides of the coupling are centered using a dedicated tool, ensuring concentricity.
Blocks heat
A stainless steel disc spring is used for the element, so heat from the servo motor does not readily transfer to the driven shaft, reducing inconsistency in precision caused by thermal expansion.
For tapered shafts
Allows coupling via a clamp hub when an optional taper adapter is mounted on the tapered shaft of a servo motor.

It can be very difficult to fully center two shafts when connecting them together. Shaft deflection caused in operation of the machinery, thermal expansion of the shafts, warping of support plates over long periods of use, and wear of shaft bearings can also make it difficult to keep the shafts centered. The role of the coupling is to resolve these types of problems through the selection of the right coupling for the job. Miki Pulley provides a wide range of coupling products not just for general purpose motors, but for everything from servo motors, which demand ultra-precise control, to engines, which generate high vibration and large shocks.
