    Product Description

    Product Features

  • Solid and split covers handle high speeds and torque
  • Design dampens torsional vibration and shock
  • Accepts shaft misalignment up to 2 degrees
  • Eliminates the need to move or disassemble the driving or driven equipment to replace the coupling insert
  • Versatility of design makes it a great tool for plant standardization
  • Accepts shaft sizes from 10 ~ 285 mm (0.37 ~ 11.25")
  • Peak handling torque from 0.085 ~ 377.5 knm (754 ~ 3,341,562 in.-lbs.)
  • Standard and double-ended spacer couplings available for shaft separations of 25.4 to 3,048 mm (1 ~ 120"), for increased application acceptance
  • Four bore options available to meet customers’ needs:
    1) Bored, keyed and set screw style ~ clearance or interference fit
    2) Bushing style (Dodge®, Browning® & QD style taper lock bushings)
    3) Splined style
    4) Mill-motor style (tapered shaft)
  • Stainless steel versions available for corrosive environments
  • Four insert choices for varying torque needs and temperature ranges, up to 177°C (350°F)
  • Replaces many common gear, grid and elastomeric couplings used in high and low torque applications to reduce plant complexity
  • Inherently balanced from precision machining of all components
  • Split-cover options help resist axial separating force under high torque
  • Standard finished bore hubs are supplied with a clearance fit and should slide onto the shaft without excessive force. There is no suffix designating a clearance fit
  • If the hub has been ordered with interference fit, designated by the suffix "U", then industry standards suggest heating the coupling halves to approximately 300° C (572° F) before installing on shafts. If they are not heated properly, the couplings will not fit on the hub properly

  • Timken’s Quick Flex® Elastomeric Coupling Configurator helps you quickly size Quick Flex coupling solutions for common applications.
  • By entering motor power (HP or kW), speed (rpm), and service factors, the configurator presents available Quick Flex coupling options, supporting faster selection and quoting.
  • Access the Quick Flex® Coupling Configurator to speed up your next coupling selection.
