The new SJL six-jaw chuck from SMW‑AUTOBLOK offers the highest accuracy for the sensitive clamping of workpieces sensitive to deformation. The SJL is a 2 + 2 + 2 lever compensation chuck and achieves high concentricity and axial runout accuracies. It is switchable from 2 + 2 + 2 lever balance to 6-jaw centric tension. This means that the customer can also clamp 6-jaws centrically with the SJL chuck. The SJL six-jaw chuck is sealed and protects the interior from the ingress of dirt and cooling water. In addition, the chuck has a permanent lubrication with oil. This allows for long maintenance intervals. The lining also has centrifugal force compensation and is suitable for high speeds. The new SJL is now available from stock in sizes 225 and 290.
