MD Series - Mini Disc Clamp Style Couplings - Inch (Imperial) Bores
Mini Disc Style Couplings (MD, MDS & MDSD Series)
-
The MD (mini disc) Series coupling features a higher torque capacity over elastomeric
coupling types. The MD Series one piece clamping design allows for easy removal and
assembly. The Aluminum hubs and stainless steel disc materials allow for excellent
resistance to oil and other chemicals.
The MD Series design offers moderate torsional stiffness for applications requiring repeatability. The MD Series also offers up to .020 inches of axial misalignment.
