	MC Series

Features Relevant Links & Charts Industrial motor shaft couplings Large parallel misalignment capacity High torque capacity Large shaft diameters Keyways available MC Series Special Bore Configurations MCAC Series Chart  MC7C Series Chart MCA Series Chart MC7 Series Chart  Standard Coupling Guide 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/coupler will fit your needs.  Available in 7075-T6 aluminum alloy or 17-4 PH corrosion resistant steel (CRES).

Attachment Methods Internal Configuration Integral Clamp / MCAC & MC7C  Set Screw / MCA & MC7 (two each end @ 120º) Relief * Major and minor diameter shafts may enter flexure area during operation * Dark areas indicate the amount of relief within the coupling interior

How to Order Coupling part numbers consist of four sections. To determine the correct numbers/letters for each section of a specific coupling part number, please refer to the charts on the following pages. Example **Refer to "Standard Bore Diameters" section of chart 1. Basic Model Number:  Choose material and attachment method. MCAC = Aluminum, Integral Clamp MCA =    Aluminum, Set Screw MC7C =  Stainless Steel, Integral Clamp MC7 =     Stainless Steel, Set Screw 2. Outside Diameter Designator: This three-digit number represents the coupling/coupler outside diameter. Based on the Performance Data in the middle of the chart, select the Outside Diameter Designator by moving left to the appropriate diameter. 3. Major Bore Designator: The larger of the two bores, its diameter is expressed in either 32nds of an inch (-8 equals 1/4 inch) or in millimeters (6mm). Please review your selection to determine if both bores can be made in the size coupling you have selected in 2. It is important that the larger bore be stated first. 4. Minor Bore Designator:  The smaller of the two bores, is expressed the same as the Major Bore Designator. Either bore can be inch or mm.
