Power chucks 3QLC / 3QLK
  • Innovative (patented) multiple base jaw profile with improved guiding length for greater stability and precision during internal and external clamping
  • Minimal loss of lubricating grease through gaps and undercuts, because jaw guides are precision ground, reducing maintenance and increasing consistency
  • Best possible clamping forces are obtained through multiple jaw guides
  • Improved lubrication with additional, integrated lubricant reservoir and improved forced circulation
  • Patented backlash free wedge hook mechanism for maximum clamping forces and highest repeatability
  • Centrifugal force compensation for highest speeds (QLC version)
  • Selected matching highest quality materials – all loaded, sliding surfaces are hardened and ground
  • Simplified construction of the guiding piston in the chuck
  • Base Jaw serrations according to European and US specifications available as standard
  • MIR / ZMIR quick jaw change system optional
