The Schunk ROTA NCO 500 is a large 19-3/4 inch (500 mm) 3-jaw hydraulic power chuck engineered for heavy-duty, large-diameter workholding on big-bore CNC turning centers. It develops up to 140 kN of draw-bar force for 330 kN of total gripping force and spins to 2,000 RPM, securing massive shafts, flanges, and cylinders with self-centering repeatability. Schunk is a world leader in workholding and automation, and the ROTA line is known for high force, precision, and long-term reliability. This chuck is built for serious metal removal on large parts. Compared with a manual chuck, this hydraulic power chuck delivers consistent, operator-independent clamping cycle after cycle, and its enormous 330 kN gripping capacity holds heavy work that smaller chucks cannot safely turn. At 500 mm, it is purpose-built for large-frame lathes and heavy production. Bought used, this Schunk chuck brings world-class, large-capacity workholding to a CNC lathe.
