More Information on Rodless Air Cylinders
Rodless cylinders are a compact alternative to standard rod-style cylinders. The stroke of a rodless cylinder is contained within it's body length which makes rodless cylinders about half the length of conventional cylinders. Rodless cylinders are generally used in long-stroke shuttle applications, but they have many applications.
Band cylinders have a carriage that rides along the outside of a tube with a longitudinal split in it. The piston rides inside the tube and is attached to the carriage through the tube's split. A band covers the split to seal the tube. As the carriage moves along the tube, the band is unseated and then reseated as the carriage passes. The band is not able to create a perfect seal, therefore there is always a very slight leak from band cylinders.
Cable cylinders use a piston with aircraft cable attached to both ends of it. The cable travels from the end of the piston, through a gland seal in the cylinder's end cap, around a pulley, and connects to a yoke that travels along the length of the cylinder. As air is input into the left end of a cable cylinder, the piston travels to the right which pulls the yoke to the left.
Magnetically coupled cylinders use a piston that has very strong, rare earth magnets attached to it. The carriage that travels outside the tube is magnetically coupled to the piston inside the tube. As the piston travels back and forth within the cylinder tube, the carriage travels with it. Magnetically coupled cylinders are leak-free since there are no leak points. In tough applications, the limiting load capacity of the cylinder can be the strength of the magnet.
