Double acting pneumatic cylinders

compact, series MCKJQ3 with non-rotating rod

A series of cylinders with a piston rod secured against spontaneous rotation. The piston rod has a hexagonal shape and may only be loaded up to the permitted torque value. This series can be used wherever short installation dimensions are required. The cylinders do not have end position damping. They can be equipped with a magnet for proximity position sensing.
