K1 series hollow piston rod pneumatic cylinders are actuators that move a load in a linear way and allows to transfer a general gas (air-vacuum) from a special port "A" on the read end cap along the piston rod "B".
These important features allow to operate without any pipe around the working area. They are available in 5 sizes (25 (not cushioning) ,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.
The K1 series cylinders are a valid alternative to holed through rod cylinder as they have dimensions longitudinally more compact.
The following drawings are useful to explain the way to use these that cylinder.
