Mini Disc Style Couplings (MD, MDS & MDSD Series)
-
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.
