Rodless cylinders are pneumatic drives and – as the name suggests – do not have a piston rod. Although they don't have a piston rod, they execute linear movements, which is why they are also known as linear drives. Rodless cylinders are used wherever a short installation length is advantageous and where the force has to be absorbed as consistently as possible. They also allow much longer travel distances with strokes of up to 8.5 m, which is not feasible for a standard cylinder with piston rod.
