SK COLLET CHUCKS
SK COLLET
SK Collets can be used for all applications, from milling to reaming. Mechanical sealed collets can be used in coolant thru applications.
SK Collet vs. ER Collet
A. Wide collet = wide nut = less clearance B. Angular compression creates more runout C. Shallow seating allows for collet rocking with more runout, less repeatability
A. Compact design allows for better clearance B. Straight compression prevents collet rocking, creating better accuracy C. Deeper seating creates greater accuracy and repeatability D. Body and nut are flush for more rigidity A

LYNDEX-NIKKEN Slim Chuck - Flat Shoulder Pushing
OTHERS Taper Shoulder Pushing
Complicated Nut: balancing will be changed during high-speed rotation
Wider angle collets can misalign causing poor run-out and gripping force
8° taper creates double the gripping force of ER
Simple and rigid nut
• High accuracy due to flat shoulder pushing
• Unstable run-out due to taper part pushing • Poor gripping torque of 12º, 16º taper
