Power chucks with quick jaw change system

The DURO‑A RC self‑centering automatic chuck from Röhm is engineered for lathes to ensure secure holding and exceptional repeatability in precision machining. At its core lies the quick‑change jaw system with individual jaw release, enabling each jaw to be exchanged, repositioned or rotated flexibly in only 50 seconds while maintaining the original calibration of the chuck.

Its redesigned housing reduces total height by up to 14 % and weight by up to 17 % compared to similar‑power chucks, enhancing centrifugal behavior and permitting high rotational speeds. Despite its lightweight, compact form, the DURO‑A RC delivers impressive clamping forces and features a large through‑hole for efficient bar, tube and flange machining.

The jaw locking and unlocking process is both simple and secure: insert the safety key until it stops, then turn in the direction of the arrow to release an individual jaw, even when using oversized special jaws for very large workpieces. Jaws can be mounted via a cross‑dovetail interface or as integral units, depending on the clamping requirements.

Standard delivery includes the DURO‑A RC chuck, mounting screws for the jaws, jaw bases, a safety key and an assembly key—everything needed for immediate setup. With its blend of speed, flexibility and precision at an attractive price point, the DURO‑A RC is the go‑to solution for industrial turning applications demanding rapid tool changes and uncompromising accuracy.
