CJ Series Design / Elastomers ■ Three piece design that is easy to assemble ■ The curved jaw design incorporates both radial and axial curvature (crowning) to the elastomer (spider) ■ Hubs are offered in sintered iron, steel, aluminum, cast iron and nodular iron materials ■ Three different urethane elastomers available ■ No metal to metal contact and no lubrication required ■ Fail safe design due to the jaw in compression design (continues to function after the elastomer fails) ■ The CJ series covers a torque range of 67 to 247,800 in-lbs ■ Four types of spiders are available for the CJ Series...

Selection Process Steps In Selecting A Curved Jaw Coupling Step 1: Determine the nominal torque of your application: Step 2: Calculate your Application Service Factor using the charts below. The total Service Factor (K) will be: Step 3: Calculate the design torque (DTkmax) of your application. Design Torque (DTkmax) = Nominal Torque x service factor. Step 4: Using the Elastomer Torque Ratings Tables on pages CJ-6 and CJ-7 select the urethane shore hardness which best corresponds to your relative damping needs in the application. Step 5: Next find the columns listing Tkn and Tkmax values listed...
