RÖHM DURO-A 254 power chuck, 60-degree pointed teeth, cylindrical shank ZA 220

The Duro-A is a three-jaw through-type chuck that can be operated automatically, i.e. hydraulically, by a CNC machine. It is primarily used for turning operations on cylindrical and disc-shaped workpieces. Technical features: high flatness and concentricity accuracy; high repeatability; consistently high clamping force over 500,000 cycles; wedge hook principle; Fixed base jaw, top jaws via slotted nuts; threaded ring pre-fitted Applications: Premium through-type power chuck for machining bars, tubes and flange-type workpieces with a constant clamping force curve over 500,000 cycles. Advantages: High clamping forces (up to 250 kN in the 400 series version); high rotational speeds (up to 8,000 rpm in the 165 series version); reduced interference contour; large through-bore. Further information: The Duro-A, diameter 254, is a three-jaw chuck with a through-bore diameter of 79, a cylindrical shank ZA 220 and 60-degree pointed teeth, which can be operated automatically, i.e. hydraulically by a CNC machine. It is primarily used for turning operations on cylindrical and disc-shaped raw parts.
