- 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
