Disc Coupling

Our oiless DC Coupling provides exceptional high-speed performance and is designed for easy maintenance.



  1. No need for lubrication:  Since their is no site of friction or rolling, lubrication is not necessary.
  2. Maintenance-free:  under the normal operation, only the inspection to loosen bolts and nuts will be necessary.
  3. Zero backlash:  A precise phase control will be secured due to high rotation uniformity caused by no backlash and strong torsional stiffness.
  4. High torque transmission: Due to its optimal design and compact size,  our DC coupling provides high torque.
  5. Easy mounting/dismounting:  Our product consists of disk element, bush and washer in a package, so the connection or removal of coupling can be done easily.
  6. High allowable rotation frequency:  Our high-precision bush is inserted between the element and bolt, enabling it to be ued at extremely higher speeds in comparison to other couplings.
  7. Large allowable misalignment:  Its allowable misalignment is large enough at 0.5~1° in deflection angle. Furthermore, its allowable parallel eccentricity can be adjusted according to the spacer length.
  8. Light thrust load:  As the thrust load generated from coupling is light, burdens of drive shaft and bearings can be extremely minimized .
  9. Plentiful inventory:  DC coupling and its parts are in good stock and can be supplied immediately through our sales network
