  • Compensating chuck to clamp off-center parts with high precision
  • Easy moving compensation even at high clamping forces
  • Ingenious pull-back action for improved part location on center
  • Easily interchangeable and finely adjustable center housings
  • Simple change-over for self-centering mode for general chucking work
  • Innovative (patented) multiple base jaw profile with improved guiding length for greater stability
  • Centrifugal force compensation for highest speeds (QLK variants not available)
  • Axial stroke limitation is integrated, ensuring any over stroke of the cylinder is not problematic
  • Jaw guides are precision ground with a circular profile
  • Minimal loss of lubricating grease through gaps and undercuts, because jaw guides are precision ground, reducing maintenance and increasing consistency
  • Nitrided chuck body for longer service life
  • Selected matching highest quality materials
  • all loaded, sliding surfaces are hardened and ground
