Rodless pneumatic cylinders are particularly useful when long stroke lengths are required, in a restricted space. In the UK, most Camozzi rodless cylinders are built in our Midlands based workshop and are available with next day despatch.
How do rodless cylinders work?
A rodless cylinder is a pneumatic component capable of moving a load in a linear path with compressed air. Where a traditional pneumatic cylinder uses a rod to push or pull the load from the piston, a rodless cylinder moves the load alongside the piston.
With rodless cylinders, an internal piston moves within the cylinder barrel and is driven by compressed air. The piston is attached to a carrier. This carrier supports the mounted load and moves with the piston. The metal bands allow the carrier to move back and forth while creating a reliable sealing of the cylinder slot. Under the carrier, the bands are bent away from the slot to allow a connection between piston and carrier. But the fact that we have metal bands that are working as seals, gives us a small constant leakage making it harder to control, especially when mounted in a vertical position.
What are the advantages of rodless cylinders?
Because a rodless cylinder moves the load alongside the piston, the main advantages are less space requirements, no rod buckling to worry about with high loads or long strokes, and it delivers the same force in both directions. The rodless cylinder is most commonly used for applications like material handling, loading, lifting, web cutting, etc.
