The SCHUNK ROTA NCO chuck has a high clamping force, low jaw stroke, and low height, ensuring more space in the engine room, short cycle times, and high versatility.

For economical productivity, the NCO offers several advantages: The high clamping force and large jaw stroke guarantees secure clamping across interfering contours and ensures maximum versatility. In I.D. and O.D. clamping, long base jaw guides support the chuck jaws so that high clamping forces are permanently maintained.

The relatively low weight of the lathe chuck reduces the mass that is moved during processing, allowing faster acceleration and deceleration in comparison to other chucks, which saves energy, shortens cycle times, and increases productivity.

The jaw interface is optionally available with a fine serration of ¹⁄₁₆" x 90 degrees or 3/3" x 90 degrees or with a metric tongue and groove. Adjustable bronze wiper strips seal the base jaws against water and dirt.
