It combines the best features of the A Series and the H Series, with the convenience of metric dimensions and fasteners for your metric based designs. The W-Series can be used in a wide range of applications from driving components with light torque requirements, such as encoders and tachometers (aluminum), to lead screws and pumps requiring greater torque (stainless steel).

How to Order Coupling/Coupler 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 attachement method. WAC = Aluminum, Integral Clamp WA =    Aluminum, Set Screw W7C =  Stainless Steel, Integral Clamp W7 =     Stainless Steel, Set Screw 2. Outside Diameter Designator: This two-digit number represents the coupling 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 millimeters (6mm) or in 32nds of an inch (-8 equals 1/4 inch). 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, it is expressed the same as the Major Bore Designator. Either bore can be inch or mm. Please specify mm when metric.
