All chucks feature a uniquely designed 40 mm high 4-layer
needle bearing retainer to maximize the chucking force.  
Needle bearing is 7 mm in length.  Each needle bearing
retainer contains:
  • 200 needles in Chuck ASC25
  • 220 needles in Chuck ASC32
  • 280 needles in Chuck ASC42
for a wide contacting area and, thus, to increase the chucking
force to the maximum.
