The CAS series, manufactured by Clamptek, is a pneumatic cylinder. Its body has been constructed out of aluminum alloy, the surface has been processed with hardening substances providing a long service life. The length of the clamping arm can be extended up to 1.5x its original length. When the piston pushes down, the clamping arm will rotate to the designated angle then it will push down in a straight line to hold the workpiece. Furthermore, it is ideal to integrate a flow control valve to adjust llu-acting speed.
