Retention Force Dynamometer
Dyna Force Measuring device for pulling force of machine tool spindle.
Belleville Springs
• Periodical measurement avoids reduced rigidity leading to vibrations, loss of machining quality, shortened tool life
Collet Longer taper shank to e nhance reliability Long taper supports itself in long span and stabilizes the value of measurement.
Only one display for all taper sizes One common display can be used for all taper sizes.

Each component is also available separately. Please contact BIG KAISER agent if individual component is required. SBT30-DF10 is designed exclusively for machines not capable of automatic tool change. SBT30-DF10 is suitable for BT/BBT30 machines only. Pull stud bolt is to be ordered separately. For DIN, ISO, ANSI & CAT standard machines, e xclusive pull stud bolt for dyna force is required. SNT50-DF30 marked with * is a light-weight model.
Exclusive pull stud bolts for Dyna Force An exclusive pull stud bolt is needed for a machine spindle in DIN, ANSI or CAT standard. Pull stud bolts in MAS and JIS standards can be used. These pull stud bolts are not suitable for the SBT30-DF10. Standard No. DIN69872 ISO7388 ANSI B5.50 ASME B5.50
