"K1" series hollow piston rod pneumatic cylinders are actuators that move a load in a linear way and allows to transfer a general gas from a special port on the read end cap along the piston rod.
These important features allow to operate without any pipe around the working area. They are available in 4 sizes (32,40,50,63 mm) and are cushioned and arranged in order to use magnetic switches. Overall dimensions are like ISO 15552 standard cylinder except for the piston rod thread, therefore they can use the same fixing accessories.
