Rodless Air Cylinders

Rodless air cylinders use compressed air to drive equipment and machinery without a rod. They consist of a cylinder and an internal piston connected to an external carriage by magnets, cables, or sealing bands. Magnetic rodless air cylinders have thinner cylinder walls that allow external magnets to pull the piston assembly’s internal magnets down the length of the stroke. The cabled version uses two cables inside the cylinder to smoothly move the assembly. Rodless air cylinders with sealing bands use one band to prevent internal air from escaping and the other to protect the slot and first band. Rodless air cylinders take up less space than standard air cylinders and are ideal in applications that require long stroke lengths.
