Special seals on the guideways prevent grease from washing out under coolant pressureClick image to enlargeSchunk’s ROTA-M flex 2+2, is a low-maintenance chuck jaw with a compensating mechanism that provides a very long compensation stroke.

Depending on the size, it amounts to 5.1 mm up to 10 mm per jaw, increasing flexibility for clampable workpiece geometries in a wide variety of possible applications.

In many cases a single ROTA-M flex 2+2 chuck will be sufficient for covering a wide range of part geometries.

Special seals on the guideways prevent grease from washing out under coolant pressure, which reduces clamping force. Even in case of low clamping forces, precise functioning of the chuck is ensured.

At the same time, the sealings protect the chuck body against chips and dirt, process safety increases and maintenance intervals are extended.

For increased safety, the clamping is done in a self-locking manner, and the clamping condition is signaled via indicating pins. The standard chuck sizes 260 to 1200 achieve jaw strokes from 9.5 mm to 17.8 mm and high clamping forces from 100 kN to 180 kN.

Starting at size 800, users benefit from a weight-reduced design. The chuck face is equipped with grooves, and fixed stops allow the chuck to also be used as a vise. Moreover, the large sizes are designed for use on vertical lathes. It’s equipped with a flexible serration (1.5 mm x 60° or 1/16-in. x 90°)
