SPEEDAIRE double-acting air cylinders are used to imply force with a piston to move an object. They use compressed air to apply the force, while the adjustable cushion dampens the force. These air cylinders are made from aluminium and are designed with a replaceable rod gland to allow a full range of NFPA MS4 interchangeable mounting configurations. They can be easily mounted with the help of 4 internal-threaded sleeve nuts recessed in the head and 4 tapped holes in the cap. Choose from a wide range of air cylinders, available in aluminium and steel piston constructions on Raptor Supplies.
