  • MD Series - Mini Disc Clamp Style Couplings - Imperial
  • MD Series - Mini Disc Clamp Style Couplings - Imperial-2
    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.
