With centrically compensating 4-jaw chucks, various workpiece geometries can be precisely and efficiently clamped on mill/turn centers, among other things. To meet the increasing demands of the market, SCHUNK has developed the low-maintenance 2+2 jaw chuck SCHUNK ROTA-M flex 2+2, which has a particularly large compensation stroke due to a patent-pending compensation mechanism.

Special seals on the guideways prevent grease from being flushed out and that the clamping force is gradually lost. Even with low clamping forces a precise function of the chuck is ensured in this way.

At the same time, the seals protect the chuck body from chips and dirt, increasing process reliability and extending maintenance intervals. The high efficiency of the wedge bar system in combination with a grease circulating lubrication system ensures reliable clamping due to high and constant clamping forces.
