K4SL series four-jaw double-action power chuck has two independent self-centering mechanisms. This product is a hydraulic 2+2 jaw power chuck, driven by a double-rod rotary cylinder. The 2, 4 jaws act together to connect the small piston of the oil cylinder for initial positioning; the 1, 3 jaws act together to connect the large piston of the oil cylinder for the final Positioning stepped up. Suitable for processing square, rectangular and other parts, and can be equipped with various forms of flanges according to requirements.
