Part Number 68514477191, MDSD Series - Mini Disc Single Disc Clamp Style Couplings - Inch (Imperial) Bores


    The compact design of the MDSD (Mini Disc Single Disc) Series accommodates applications that allow for a minimum amount of space for the coupling.

    The MDSD Series coupling also features a high torsional stiffness over the MD and MDS Series. The MDSD Series also has the lowest inertia of the mini disc designs.



Unit of Measure: Imperial Metric Both
