The Curved Jaw Design
  • 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
  • Maximum bore may be achieved through the use of a shallow keyway.
  • Maximum bore refers to maximum straight bore with keyway allowed in hub.
  • Outside Diameter is equal to Dimension HD for B style aluminum sizes: 19, 24, and 28.
  • S = Solid hub with no bore
  • Spider Outside Diameter (Dimension A) is equal to Outside Diameter
  • The values regarding displacement are provided assuming normal operating conditions (i.e. temperature, torque with nominal rating of the coupling, speed/ RPM rating of the coupling, and misalignment). Careful installation (i.e. alignment) and periodic inspection should be provided to provide the optimum life of the coupling. Special consideration should be given as to the position of the shafts and the amount of axial movement the coupling will be exposed to. The more accurate the alignment of the coupling, will result in greater life of the elastomer. A coupling guard and rotating equipment safety procedures should always be followed.
