 Download U-Clip Catalogue

With Uhing® U-Clip Uhing® set aside the easylock®  quick clamping system a simple and low-priced alternative. 

As Easylock® Uhing® U-Clip is using a clamping ring, too which is offset to the shaft and therefore clamping forces and provided. Like a bushing the Uhing®-U-Clip is pushed forward against the to be fixed component and it automatically locks into position. To release, just pull the clamping ring towards the user.


Area of application:

  • Positioning on rotating and non-rotating shafts, e.g. wind-up and pay-off (not appropriate for torque transmission)
  • Tube to shaft (or tube) connection, e.g. tripods
  • Fixing components on shafts, e.g. dumb-bell weights
  • Quick adjustment for material guiding, e.g. packaging machines


  • Usage on hardened and soft surfaces
  • Self locking
  • One hand operation
  • Symmetrical design
  • High self locking force compared to ball systems with inclined level
  • Corrosion protected 
  • Resistant against vibration

UC8-16: place thumb and index finger into the represses grips and push the clamping ring simultaneous down. Slide then the Uhing®-U-Clip on against the to be fixed component or pull it off easily without any resistance. After that release the grip.

UC20-35: press on release button for free movement.

Tolerance of diameter: h6 - h9

Holding force:
Specification refer to the usage of surface hardened shafts with a hardness of min. 50 HRC. In case of unhardened shafts clamping force should be reduced by 20% to prevent damage of the shafts.

Operation temperature:  max. +50 °C

Operation advice:

If after the locking of the Uhing®-U-Clip  a rising of the counterface happens, i.e. an extension of the spool, the releasing of the U-Clip can be complicated. The Elasto-Ring can remedy it.

We reserve the right to make technical alterations.
