  • Industrial motor shaft couplings
  • Large parallel misalignment capacity
  • High torque capacity
  • Large shaft diameters
  • Keyways available
This versatile series of couplings provides you with a full range of torque capacities and bore sizes, all with 1/32-inch parallel misalignment capability. These couplings attach to shafts with your choice of integral clamps or set screws. Combine this with optional keyways and the MC Series is tailor-made for your application.

From medium-duty (aluminum) to heavy-duty (stainless steel), this series provides solutions for a wide range of applications. From pumps and lead screws to conveyors, chances are an MC Series coupling will fit your needs. Available in 7075-T6 aluminum alloy or 17-4 PH corrosion resistant steel (CRES).

Note
  1. Shaft misalignments:
    Angular 5 degrees
    Parallel Offset 0.030 in. (0.060 in. T.I.R)
    Axial Motion ±0.010 in.
  2. Manufacturing dimensional tolerances unless otherwise specified are:
    fraction ± 1/64
    x.xx ± .01 in.
  3. With integral clamp attachments only, this bore size requires an operating clearance diameter greater than coupling outside diameter.
  4. Inch and metric keyways available.

  • 1 Dynamic torque ratings are momentary values. For non-reversing applications, divide by 2. Divide by 4 for reversing applications. Should the torque ratings be marginal for your application.
  • 2 Inertia is based on smallest standard bore diameter.
  • 3 Metric fasteners available on request.
