 ▶ Cross Joint Type Flexible Coupling
 

 The precision calibration coupling of the cross joint type
which isable to absorb with little strain eccintricity and amplitude instrumentally is acoupling of unique structure combining both Oldham and universal joints which curb the generation of a resisting force delicately and absorb intake tolerances, and SUNG IL manufactures it in a simple
design in such a way thatit carries high rigidity, lowinertia andhigh resonance frequency and in which the extent of stoppage and the responsiveness of a precision position deciding instrument are enhanced.

 

 

 

    Feature

  • Identical both in a regulardirection and a reverse direction, and a unifom revolutionis available.
  • Hasexcellent durability, chemical-resistance and oil-resistance.
  • The bearing built-in in the hub andthe pin in the center block absorb big eccentricities and amplitudes
    with little stain.
  • If the pin and bearings are asseembled in a high level, it reduces back-lash to the minimum.
  • mimimizes the generationof a resisting force with its high torsionalrigidity andlow inertia.
  • Delivers a control unit angle swiftlly in a high level.
  • varied sizes are available.
